Thanks, Risto. I'll give those a try and report back.
And I want to say a public "Thanks!" as well for all your work on PowerPC Debian. I, for one, appreciate it.

Hi Rick, ehci-hcd can take three parameters: log2_irq_thresh (0-6): log2 IRQ latency, 1-64 microframes park (1-3): park setting; 1-3 back-to-back async packets ignore_oc (0-1): ignore bogus hardware overcurrent indications I don't really know what they mean, and I doubt they would help here, but it may be worth a try. You could create a new file, /etc/modprobe.d/ehci-hcd.conf: options ehci-hcd log2_irq_thresh=6 park=3 ignore_oc=1 Then execute: modprobe -r ehci-hcd modprobe ehci-hcd It can hardly get worse. uhci-hcd is always loaded: it provides USB 1.1 connectivity, i.e. speeds up to 12 Mbit/s. ehci-hcd provides USB 2.0, speed 480 Mbit/s. So it probably doesn't make sense to remove it permanently, but just for test's sake: modprobe -r ehci-hcd And permanently (/etc/modprobe.d/ehci-hcd.conf): blacklist ehci-hcd Now the device should be detected as full speed instead of high speed. Yes, full speed is much lower in this case. Risto -- To UNSUBSCRIBE, email to debian-powerpc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
