Comment 19 for bug 228746

Confirmed in Karmic: Apparently, I have the same or a similar problem on a Gateway MT6452 Notebook (AMD Turion 64 TL-52, but running 32 bit karmic). The problem either started with ibex or jaunty and seems to have gotten worse with karmic. I have 4 usb ports. Sometimes one will just die and the problem can be remedied by switching to another; other times, all four will die or all four will be dead upon reboot. A new problem has emerged with karmic, which is that wireless via usb will be unstable. I'm happy to post any outputs, but will need instruction as I'm a fairly naive user. Upgrading my BIOS isn't really an option for me, or at least one that I'm willing to try. As with other posters, lsusb will hang on me.
