Hello,
just a question. Has anyone usb-devices working on a current-smp
(very recent current, but problem exists since I can remember)
system? On my Abit VP6 (Via-Chipset) a USB-Mouse and USB-Printer
do work fine if I boot a single-CPU kernel. With a SMP-Kernel
I am getting messages like:
Nov 10 15:53:38 pc-micha /boot/kernel/kernel: uhub0: device problem, disabling p
ort 2
Nov 10 15:53:56 pc-micha /boot/kernel/kernel: uhub1: device problem, disabling p
ort 2
and obviously the USB-Devices do not work.
With a single CPU-Kernel usbdevs delivers
pc-micha:/home/michaelc# usbdevs -v
Controller /dev/usb0:
addr 1: self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 0x0100
port 1 powered
port 2 addr 2: self powered, config 1, DeskJet 990C(0x3304), Hewlett-Packard(0x03f0),
rev 0x0100
Controller /dev/usb1:
addr 1: self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 0x0100
port 1 addr 2: low speed, power 100 mA, config 1, Genius USB Wheel Mouse(0x0003),
KYE(0x0458), rev 0x0000
port 2 powered
This is the dmesg-frgment from a single CPU-Kernel for usb:
uhci0: <VIA 83C572 USB controller> port 0xc400-0xc41f irq 10 at device 7.2 on pci0
usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
uhci1: <VIA 83C572 USB controller> port 0xc800-0xc81f irq 10 at device 7.3 on pci0
usb1: <VIA 83C572 USB controller> on uhci1
usb1: USB revision 1.0
ums0: KYE Genius USB Wheel Mouse, rev 1.00/0.00, addr 2, iclass 3/1
Any Ideas?
Michael
