Dear all, I've just started experimenting with USB on Linux, in particular because I want easy access to removable storage devices which can be supported both on a laptop and on a desktop computer.
I'm seeing several problems one which worries me a lot is an error message like this when the laptop boots; uhci.c: fce0: host controller halted. very bad I've looked at the source code around this message but I'm not familiar enough with USB to know what it means. Please can someone explain what's going on here and whether it really is "very bad"? A full capture of the boot messages related to USB is on the end of this email. The laptop is a Dell Latitude LS. 'lspci' says that the USB controller is 00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) The Linux distribution is Suse 7.0 which I've upgraded to Linux kernel edition 2.4.13. I've not checked the USB CVS for anything more recent than what comes with the kernel or looked at ac series kernels.
