I've been dealing with the below problem for about 5 days now.. I'm really completely unsure as to what to do next.
At seemingly random points during normal computer usage, my usb completely stops working. It happens sometimes after 10 minutes of usage, but sometimes after hours of use. The only consistency that I can find is that it fails while i'm actively using it.. I never come back to my idle computer to find it disconnected.. and I always notice that it is disconnected because my usb mouse freezes in my movement. The entire usb controller stops working.. My intellimouse explorer optical light is off, and I can no longer connect to my USB digicam. I think those are the only usb devices I have to test with. The important section of my dmesg is pasted at the bottom of the email. This problem did not happen with any of the 2.4 kernels.. I had used several standard and patched 2.4 kernels. There have been no significant hardware or software changes, other than the upgrade to a 2.6.0-test9. I'm currently using 2.6.0-test9-mm4, but it also happens with 2.6.0-test9-mm2. I'm not intimately familiar with kernel workings, but from a quick read through the mm-series changelog, I can't see anything in it that would indicate possibly causing this problem. I've tried recompiling with usb, hid, uhci as modules instead of builtin.. still freezes.. and then when i rmmod then, lsmod output freezes after the column headers. I fear that my only source for a solution will be to post a kernel bug, so if that seems like what i should do right now, can anyone advise me on that process.. what information should i supply? (i.e. how can i best deliver debugging info) here's some important dmesg: -------------------------------------------- hub 2-0:1.0: new USB device on port 2, assigned address 3 usb 2-2: USB disconnect, address 3 hub 2-0:1.0: new USB device on port 2, assigned address 4 usb 2-2: USB disconnect, address 4 hub 2-0:1.0: port 1 disabled by hub (EMI?), re-enabling...<6>usb 2-1: USB disconnect, address 2 hub 2-0:1.0: new USB device on port 1, assigned address 5 usb 2-1: control timeout on ep0out -------------------------------------------- Other info about my system.
