Venom Rothery Posted March 6, 2015 Share Posted March 6, 2015 Hi everybody, I'm currently busy building my own cockpit, and I've bought two Cougar MFDs along with two 8" Lilliput UM-80/C/T monitors. When I attached the first of the displays to my 10-Port powered USB hub (Icy Box IC-AC6110), it said there were not enough resources to power the device. :( When I disconnected everything else on this hub, it worked. But when I connected the second monitor, it complained again. It seems that even hooking up the two displays to a separate 4-Port USB hub is not an option if they draw that much power from the USB bus. I have noticed however that the monitors have an extra power connector next to the Mini-USB connector. Is it possible to connect separate 5V 500mA power supplies there and just use USB for the display data? Does anybody have experience with this? //VR :helpsmilie: Link to comment Share on other sites More sharing options...
Laurius Posted March 6, 2015 Share Posted March 6, 2015 Hi and welcome Have you tried to connect both Lilliput and their power cables directly to your PC's USB ports ? That's how mines are connected.

Venom Rothery Posted March 6, 2015 Author Share Posted March 6, 2015 Hi Laurius, that would surely work, but I forgot to mention that my PC is a dual-use machine. I switch my boot SSDs rather frequently and I don't want to rewire the whole box each time I do this. Two or three USB hub cables and a powerboard for additional monitors are OK, but any more than that means hard work ;) - especially as I have to keep track where which USB plug goes. If I don't pay attention, my X-45 and my Saitek pedals will conflict (at least in Star Citizen they do.) So I'm looking for some sort of low-maintenance solution. Sorry for not mentioning this earlier. Reading this helpful forum for months is one thing, but the first own posting probably gave me some stage fright :music_whistling: //VR Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 6, 2015 Share Posted March 6, 2015 Hi VR, da du aus Hamburg kommst, denke ich du sprichst deutsch... :-) Ich betreibe 3 8" Lilliput UM-80/C/T und habe damit keine Probleme... habe die ganz normal an einem 7 - fach USB Hub angeschlossen, Dieser ist allerdings ein aktiver USB-Hub mit eigenständiger Stromversorgung. Das benötigst Du, da die USB - Anschlüsse vom PC über einen nicht aktiven USB - Hub schnell überlastet sind und nicht genügend Spannung liefern. Hoffe ich konnte dir damit helfen.

Venom Rothery Posted March 6, 2015 Author Share Posted March 6, 2015 Hi Tronix, ja, ich spreche deutsch :) Und vielen Dank für die Bestätigung meiner These, dass es eigentlich gehen müsste! But maybe we'd better stick to English here... might help more people..? My hub is active, it has its own power supply - and still there's not enough juice for 2 monitors, that's what's troubling me :cry: What brand/type is yours? //VR Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 6, 2015 Share Posted March 6, 2015 (edited) okay, then it'll continue in English ...:-) So I have the following active HUB. http://www.amazon.de/gp/product/B007TPFXEC?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00 Once a variant 7 Port and 2 x 4 port. on the 7 port I have two 8 "Lilliput and a 4-port the other 8" Lilliput. in addition, the MFD Cougar Thrustmaster Hotas Warthog and the Logitech G13 and Advance Gameboard. Maybe your active USB - Hub too weak, have my 12V and 3A. Runs without problems ... :thumbup: Many Greetings, Tronix Edited March 6, 2015 by Oldcooltronix [sIGPIC][/sIGPIC] my DCS World - Ka50 Pit Project: :pilotfly: http://www.ka50.de Link to comment Share on other sites More sharing options...
cichlidfan Posted March 6, 2015 Share Posted March 6, 2015 Hub power supplies can vary quite a bit. I was poking around in my setup yesterday due to an apparent hub power issue. The hub in use, 7 ports, had a 2.5A PSU while the replacement, also 7 ports, had a 4A PSU. Unfortunately, even that doesn't really tell you how much power each individual port can supply. Sometimes the manufacturer provides port specific information but, most often, they don't.

Extreme 8GB, Corsair HX1000i, Phillips BDM4065UC 40" 4k monitor, VX2258 TouchScreen, TIR 5 w/ProClip, TM Warthog, VKB Gladiator Pro, Saitek X56, et. al., MFG Crosswind Pedals #1199, VolairSim Pit, Rift CV1 :thumbup: Link to comment Share on other sites More sharing options...
Venom Rothery Posted March 6, 2015 Author Share Posted March 6, 2015 Danke, Tronix :thumbup: Just placed my order for 'your' hub, along with a 3m cable. By the way: I asked Lilliput support if they recommend using a separate power supply. And guess what: they even sell them ;) http://www.lilliputdirect.com/monitor-accessories/batteries-and-power-supplies?product_id=104 But that's ~21 Euros apiece plus shipping while the Anker hub is cheaper and gives me a few more USB ports. As cichlidfan pointed out, it's still a bit of guesswork, but Tronix is now my reference :D Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 7, 2015 Share Posted March 7, 2015 okay... :thumbup: Keep me up to date times if it would work with the new HUB... :joystick: Many Greetings, Tronix [sIGPIC][/sIGPIC] my DCS World - Ka50 Pit Project: :pilotfly: http://www.ka50.de Link to comment Share on other sites More sharing options...
Venom Rothery Posted March 10, 2015 Author Share Posted March 10, 2015 (edited) :( NOPE :helpsmilie: Same result. Your hub recommendation also doesn't cut it. The monitors only seem to work when they're connected directly to the PC's port. WTF? I plugged one into the Anker hub, just one - even that didn't work. First I get 'device not recognized', and then 'not enough controller resources'. Same as my Icy Box hub. And now for the really weird part: I found an old Hama USB 2.0 hub with 3 ports on my shelf. I connected it via USB (it has no own power supply), plugged one monitor in and bang! there it is. (If it had 4 ports, I'd also plug in the second one, just for fun.) Now what? Is it some strange USB 3.0 issue maybe? Anyone? :dunno: EDIT: The anker hub doesn't make any "connected" sound when I plug it in - is this normal behaviour? The others "ping". It lights up though. The problem might be there..? EDIT #2: Windows 8.1, not Windows 7. Some Power management stuff? //VR Edited March 10, 2015 by Venom Rothery Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 11, 2015 Share Posted March 11, 2015 strange ... :( I have win 7 and as I said because it works without problems ... I can not say anything to the 8.1 power management to win, because I do not win 8.1. because to me there are too many problems with other drivers. have you possibly a laptop or another PC to which you can test it with the monitors? perhaps also your mainboard is a problem with the USB - port ... I would do once the test with another PC, or possibly win 7 install paralel to determine the source of error. That reminds me of a straight, you have the latest DisplayLink driver installed? You need for the function Lilliputs. :doh: http://displaylink.com/support/downloads.php Then everything should work ... :thumbup: [sIGPIC][/sIGPIC] my DCS World - Ka50 Pit Project: :pilotfly: http://www.ka50.de Link to comment Share on other sites More sharing options...
Venom Rothery Posted March 11, 2015 Author Share Posted March 11, 2015 Hey Tronix, if the main difference between our setups is the OS, then I'm almost 100% sure it's because of the USB power management in Windows 8.1. I'm still at a customer's site at the moment, but I will test and play around with the power settings as soon as I get the chance. My DisplayLink drivers are current (7.7 M4, that's why I know that the monitors work at all...) I'll report on my progress soon. //VR Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 11, 2015 Share Posted March 11, 2015 okay ... :thumbup: use google, there are safety with other users of win 8, so have a problem... :huh: what you can still do the latest USB to install drivers for your motherboard... many greetings Tronix [sIGPIC][/sIGPIC] my DCS World - Ka50 Pit Project: :pilotfly: http://www.ka50.de Link to comment Share on other sites More sharing options...
Venom Rothery Posted March 11, 2015 Author Share Posted March 11, 2015 SOLVED! YAY! Device Manager is your friend in Windows 8.1! ;) Under the USB Devices branch, you have to identify the correct USB hub (had to unplug everything first, there were way too many entries) and then uncheck the "Allow computer to turn off this device to save power" item in the energy options. It seems it's interpreted as "Forcefully shut down this port no matter what's connected." Reminds me of the issue with the Cougar MFDs: http://forums.eagle.ru/showthread.php?t=115816 Now it works with the Anker hub - still not with the Icy Box model, but this may in fact be due to the PSU being too weak in that one. Back to the drawing board, gentlemen. Off to more woodwork for the cockpit panels now :captain: THX again for the hub recommendation! :thumbup: //VR Link to comment Share on other sites More sharing options...
Oldcooltronix Posted March 12, 2015 Share Posted March 12, 2015 But very well ... :thumbup: problem solved, so now I also want to see pictures from the pit ...

Venom Rothery Posted March 12, 2015 Author Share Posted March 12, 2015 It's still a bit too early, Tronix ;) And I have actually disassembled many things for painting at the moment.

Oldcooltronix Posted March 13, 2015 Share Posted March 13, 2015 Looking forward to the pictures... :thumbup: what a pit because you build, so the pattern? :joystick: :D [sIGPIC][/sIGPIC] my DCS World - Ka50 Pit Project: :pilotfly: http://www.ka50.de Link to comment Share on other sites More sharing options...
Venom Rothery Posted March 13, 2015 Author Share Posted March 13, 2015 My cockpit has to work for both DCS and Star Citizen, so I'm not going for some specific plane or helicopter. I try to keep it independent. All I have right now is some old picture from five weeks ago because most is disassembled at the moment. Once everything is back in place, it will surely look better :) The seat is from a Smart ForTwo btw - lightweight and foldable ;) //VR Link to comment Share on other sites More sharing options...
