Especially with a G3 processor hooked on it. The venerable Apple Bandit PCI bridge can have some "issues" every now and then with trivial things like ... cache coherency (ugh !). It tends to hit things like USB pretty badly. I can't guarantee for sure that's the cause of your problem, but it's possible... -- benh@kernel.crashing.org The ZD1201 driver has been stable on 2.6.11.7 and i think also 2.6.13-rc6, but 2.6.14/ppc seems to have problems with that driver. I suppose i could try building up an 2.6.14/i386 and test it there if that might help... Attached are some USB kernel messages and extracts from `lsusb -v`. Thank you for your comments and assistance. -- JM ------------------------------------------------------------------------------- ... usbcore: registered new driver usbfs usbcore: registered new driver hub usbcore: registered new driver usbmouse drivers/usb/input/usbmouse.c: v1.6:USB HID Boot Protocol mouse driver ...
