I am currently using kernel version 2.4.22 with no patches on an ECS K7S5A PRO 
motherboard using the SiS 735 chipset. I have enabled USB support in the 
kernel, and have compiled in OHCI, UHCI, and EHCI (not as modules). 

When it boots, it seems to detect 5 seperate usb busses, 2 UHCI, 2 OHCI, and 1 
EHCI, but no matter what perhepheral I plug into any of the motherboard's 
ports (there are 4 of them), I get the following:

uhci.c: USB Universal Host Controller Interface driver v1.1
uhci.c: USB UHCI at I/O 0xc000, IRQ 11
usb.c: new USB bus registered, assigned bus number 4
hub.c: USB hub found
hub.c: 2 ports detected
uhci.c: USB UHCI at I/O 0xbc00, IRQ 11
usb.c: new USB bus registered, assigned bus number 5
hub.c: USB hub found
hub.c: 2 ports detected
hub.c: new USB device 00:13.1-2, assigned address 2
usb_control/bulk_msg: timeout
usb.c: USB device not accepting new address=2 (error=-110)
hub.c: new USB device 00:13.1-2, assigned address 3
usb_control/bulk_msg: timeout
usb.c: USB device not accepting new address=3 (error=-110)
hub.c: new USB device 00:13.1-1, assigned address 4
usb_control/bulk_msg: timeout
usb.c: USB device not accepting new address=4 (error=-110)
hub.c: new USB device 00:13.1-1, assigned address 5
usb_control/bulk_msg: timeout
usb.c: USB device not accepting new address=5 (error=-110)

and then the device does not respond anymore. I have tried a variety of 
devices: flash drive, mouse, playstation controller adapter, keyboard, but 
all of these seem to have the same problem. I have also tried compiling OHCI, 
UHCI, and EHCI as modules, and tried to use them seperately, but to no avail.

Could someone please tell me what is the problem with this? Could it possibly 
be a hardware problem? On my previous motherboard (had to discontinue use 
because of bad capicators) it worked fine. I have also tried to use different 
kernel versions, but it has not worked either.

Thanks in advance.
