I don't think anyone will be able to help you unless you provide more information first. The FAQ (http://www.linux-usb.org/FAQ.html) has some relevant bits, on of which I include below. A more USB-specific suggestion is to configure your kernel with "USB verbose debug messages", tweak usb-ohci.c so the "#undef DEBUG" (near the top) is "#define DEBUG", then rebuild and reinitialize everything. Then send along the relevant bits of the kernel debug output along the rest of your bug description; there will likely be something interesting there. (You might need to first tweak /etc/syslog.conf to save kern.debug output to /var/log/kernel or somesuch. - Dave Q: How do I report a bug? A: In addition to the information required in /usr/src/linux/REPORTING-BUGS, it also helps enormously if you provide the output of /proc/bus/usb/devices. If you are having problems with your host controller being recognised, it helps to have the output of lspci -v. If it is supposed to be UHCI, it helps to know whether interrupts are being generated every second. You should send this information to the user/help mailing list. If you are using UHCI, try to reproduce the problem with the "other" UHCI host controller driver (HCD). There are currently two UHCI drivers, which don't always behave the same: usb-uhci and uhci (the "alt" or "JE" driver). If you find that you have a workaround, please still report the problem! And make sure you say which HCD(s) you're using. If you have access to both OHCI and UHCI host controllers, please try to reproduce your problem with both kinds of controller. Since these use different HCDs, they may behave differently in some situations. The reason might be a device drivers assuming some HCD-specific behavior, or an HCD not doing the right thing. _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
