My USB ports randomly stop working till a reboot?
I have a HP Pavillion DV6-1149wm, Ubuntu 11.04. I have 2 USB3.0 ports, and 2 USB2.0 ports. If I use a USB port for a long period of time [e.x. with my USB WiFi adapter], that specific USB port [sometimes they stop in pairs] randomly decide stop.
After I've rebooted, everything's back to normal, but it is not practical to be rebooting all the time.
Here's lsusb [whilst only 1 out of 4 usb port work]:
matt: ~ $ lsusb

The Z-Com is my WiFi adapter, currently plugged in to my last working USB port [until I reboot]. All other 3 of my USB ports don't work. I plug in a flash drive, the light stays on, but that's it. Sometimes it will turn off about 5 seconds of being plugged in. But when I plug it in, nothing comes up on the syslog.

One note, I will say that the USB device I use most is my WiFi adapter. [Long range wi-fire] The USB extension that I use to plug it in is pretty old, and I've had to tape up the ends to keep the wire from being broken (from being moved back and forth so many times). Could plugging in a faulty USB device cause the usb port to stop working, temporarily?
Solution 1:
I came across the following in my search for info re the 'irqpoll' boot option...
Add "acpi=force irqpoll" boot options.
Somewhat contradictory to that, the answer to this question suggests using 'noacpi' instead of 'irqpoll' to fix USB problems.
