Well, depending on your chipset/drivers you use, you may want to 'use the force, read the source' from a kernel/driver perspective if all else fails? (sometimes there's a debug mode for hardware). For starters, poke around: /usr/portage/dev-libs/libusb google for 'usb diagnostic' usbview <is a basic admin tool, maybe not too diag oriented though> emerge -s usb will give you a listing of some specific applications for specific hardware. Maybe one of those applications has some advanced diags that will allow you to troubleshoot your usb subsystem, by running diags on a specific usb device? You may want to also look on the net for a 'usb sniffer' to sniff your usb data traffic. That will ensure your problem is in your hardware, and not a firmware upgrade issue to your usb(bios). Also make sure your problems are related to other usb devices and not just a single usb device. That way you have confidence that the usb subsystem is at fault and not a specific device's hardware/software. HTH, James -- gentoo-user@gentoo.org mailing list
