Hi all, ever since I run a 2.6.x kernel, my USB system keeps falling over every now and then. It did not happen with the 2.4 series kernel (I ran up to 2.4.23). I run a vanilla 2.6.7 on Gentoo.
At some point my mouse goes dead, and I have to disconnect and re-connect the USB hub to get it back to life. These are the relevant lines in the log : Jul 17 02:06:47 satan kernel: uhci_hcd 0000:00:04.2: host system error, PCI problems? Jul 17 02:06:47 satan kernel: uhci_hcd 0000:00:04.2: host controller halted, very bad! After the reconnect: Jul 17 08:17:02 satan kernel: usb 1-1: USB disconnect, address 2 Jul 17 08:17:02 satan kernel: usb 1-1.2: USB disconnect, address 3 Jul 17 08:17:04 satan kernel: usb 1-1.4: USB disconnect, address 4 Jul 17 08:17:04 satan kernel: usb 1-1: new full speed USB device using address 5 Jul 17 08:17:04 satan kernel: hub 1-1:1.0: USB hub found Jul 17 08:17:04 satan kernel: hub 1-1:1.0: 4 ports detected Jul 17 08:17:04 satan kernel: usb 1-1.2: new low speed USB device using address 6 Jul 17 08:17:04 satan kernel: input: USB HID v1.10 Mouse [Logitech USB Mouse] on usb-0000:00:04.2-1.2 Jul 17 08:17:05 satan kernel: usb 1-1.4: new full speed USB device using address 7 Full logs are on http://www.dooper.com/usb/kernel.log More info: [EMAIL PROTECTED]:/proc/bus/usb# cat devices T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 2.06 S: Manufacturer=Linux 2.6.7 uhci_hcd S: Product=VIA Technologies, Inc.
