Hi, I have a motherboard with USB 3.0 built in ( NEC chip, ) and an external USB 3 hard drive. It seems that if I boot the machine with the drive connected and powered up, the xhci driver fails to initialise and so is in effect un- usable. If I connect the drive after boot, all seems fine. This is using kernel 2.6.34-rc6 on an amd 64 system, core i7 processor. The log shows: xhci_hcd: probe of 0000:02:00.0 failed with error -110 I realise that this isn't much to go on, but equally this seems like a problem that may be known about already! So, before I give any more debugging output etc. I thought that I'd check to see if this is a known issue ( I've tried a few searches and found nothing though. ) If not, besides boot messages related to xhci and lsusb ( for both working and non working cases ) is there any more info that is needed?
