Hi, I have a palo35 board with an overo fire on it; I have a powered USB hub connected to the HOST USB port with a USB wifi radio. After running for a while the USB hub seems to crash and unmount all the devices plugged into it. I am guessing this may be due to trying to push alot of data through the hub. Has anyone seen anything like this? Could you recomend a high speed hub that works well? -- View this message in context: http://old.nabble.com/Palo35-USB-hub-crashing-tp29252699p29252699.html Sent from the Gumstix mailing list archive at Nabble.com. |

If I had to guess, I would say the problem is on the Gumstix side. Several times, with the exact same USB devices and hubs, I would get crashes and general unreliability on a Air + Tobi combo that just did not exist when I plugged everything into a laptop. I use a /Belkin Hi-Speed USB 2.0 7-Port Mobile Hub <http://www.amazon.com/Belkin-Hi-Speed-7-Port-Mobile-F5U701-BLK/dp/B000SDZ0K4/ref=sr_1_4?ie=UTF8&s=electronics&qid=1280112073&sr=8-4> (it at least looks exactly the same as the Amazon link, not sure if the models match). It hasn't caused any of the problems you mentioned though my previous statements about instability still stand. I still think it's gumstix' software at fault.

I am running my system off battery power and it turns out the battery was pretty low; that was part of the problem. I also change the kernel config and disabled CONFIG_USB_SUSPEND and the problem has gone away. I am using: http://www.frys.com/product/5660081?site=sr:SEARCH:MAIN_RSLT_PG which works well - I cut the ac adapter off and connected it directly to the 5V supply. I am running 2 cameras, a wifi radio, phidget 8/8/8 board, and GPS, sucessfully from the hub.

We're using dlink 4 port hubs (including powering the gumstix board which isn't recommneded) The dlink 4 port will supply power regardless of whether they are connected or not where as the 7 port dlinks hubs will only supply power if they are connected to a host device and its booted up.
