Hai

I put :
options pvrusb2 tolerance=2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2
in my modprobe.conf , and as it looks like now , the I/O errors are
gone , so this means a messy usb bus? I think it's the sata pci
card I had to add to be able to use my sata drives, that shares
interrupt with the usb bus. I will try to find a pata drive, and pull the
card out and see if I/O errors than stay away without having to set
the tolerance to 2.
