I am having trouble getting my Cybershot (Sony DSC-P50) camera to work under
linux. Incidentally, it didn't work under windoze (but I thought that was
because of windoze).
The machine is a pretty old 486 with a plug in PCI usb card.
Here are some relevent details from dmesg:
No local APIC present or hardware disabled
SCSI subsystem driver Revision: 1.00
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-ohci.c: USB OHCI at membase 0xc180d000, IRQ 12
usb-ohci.c: usb-00:03.0, OPTi Inc. 82C861
usb.c: new USB bus registered, assigned bus number 1
hub.c: USB hub found
hub.c: 2 ports detected
Initializing USB Mass Storage driver...
usb.c: registered new driver usb-storage
USB Mass Storage support registered.
When turning the device on I get:
hub.c: USB new device connect on bus1/2, assigned device number 2
usb_control/bulk_msg: timeout
usb-ohci.c: unlink URB timeout
usb.c: USB device not accepting new address=2 (error=-110)
hub.c: USB new device connect on bus1/2, assigned device number 3
usb_control/bulk_msg: timeout
usb-ohci.c: unlink URB timeout
usb.c: USB device not accepting new address=3 (error=-110)
And as suggested in the documentation, the card is not receiving any interrupts.
I have tried booting the kernel with noapic without any success.

Is it possible that the motherboard is just too old to support USB? Any help
would be appreciated.
