Hi James, Is anyone successfully using pvusb under 3.4-testing and 2.6.18-xen? Could you explain more details about the issue? - changeset of xen/kernel, arch (x86 or x64) - H/W (CPU, M/B, USB Host controller, ...) - USB device (Device name and VendorId/ProdId) - your setting (show me xenstore entries) The device I'm testing with is a flash memory stick, and basically the first BULK packet gets sent successfully, which I assume is a read request, and then a packet is sent to be filled with data read from the flash device and it either hangs there, or comes back with 0 bytes and then the next packet hangs - usb_submit_urb returns success but the complete callback routine is never called. Failure of the SCSI-device scanning did not occur with the storage devices that I've tested. But, this error might happen due to the mismatch of the urb->transfer_flags. I've seen this in the very early version of pvusb.

I've been trying to figure out why my windows drivers are hanging after the first or second BULK packet is sent, and only just occurred to me to see if it actually works under Linux, and it doesn't. The device I'm testing with is a flash memory stick, and basically the first BULK packet gets sent successfully, which I assume is a read request, and then a packet is sent to be filled with data read from the flash device and it either hangs there, or comes back with 0 bytes and then the next packet hangs - usb_submit_urb returns success but the complete callback routine is never called. Under Linux DomU (frontend), I get: Sep 3 20:33:12 smtp2 kernel: usbcore: registered new driver usb-storage Sep 3 20:33:12 smtp2 kernel: USB Mass Storage support registered. Sep 3 20:33:12 smtp2 kernel: usb-storage: device found at 2 Sep 3 20:33:12 smtp2 kernel: usb-storage: waiting for device to settle before scanning Sep 3 20:33:23 smtp2 kernel: vusb vusb-0: Unlink after no-IRQ? Controller is probably using the wrong IRQ. Nothing is logged in the backend. lsusb -v under the DomU appears to be just fine - everything is reported correctly. Any ideas?
