Do an "rpm -qa | grep hhl- | grep lsp". There was a hardware errata in the usb controller, but a software fix is already in the kernel (assuming you have a late enough kernel). Also, the usb switches, S4, should be set to: 1-4 off 5-6 on 7-8 off Pete > >>>> > usb.c: registered new driver usbdevfs > usb.c: registered new driver hub > usb-ohci.c: USB OHCI at membase 0xb0100000, IRQ 26 > usb-ohci.c: usb-builtin, non-PCI OHCI > usb.c: new USB bus registered, assigned bus number 1 > Product: USB OHCI Root Hub > SerialNumber: b0100000 > hub.c: USB hub found > hub.c: 2 ports detected > usb-ohci.c: v5.2 Roman Weissgaerber <weissg@vienna.at>, David Brownell > usb-ohci.c: USB OHCI Host Controller Driver > usb.c: registered new driver hid > mice: PS/2 mouse device common for all mice > NET4: Linux TCP/IP 1.0 for NET4.0 > IP Protocols: ICMP, UDP, TCP > IP: routing cache hash table of 512 buckets, 4Kbytes > TCP: Hash tables configured (established 4096 bind 4096) > Sending BOOTP requests....
