Revised: 2000-Dec-05. This is the documentation of (hopefully) all possible error codes (and their interpretation) that can be returned from the host controller drivers and from usbcore. NOTE: The USB_ST_* codes are deprecated and are only listed for compatibility; new software should use only -E* instead! ************************************************************************** * Error codes returned by usb_submit_urb * ************************************************************************** Non-USB-specific: USB_ST_NOERROR 0 URB submission went fine -ENOMEM no memory for allocation of internal structures USB-specific: -ENODEV specified USB-device or bus doesn't exist USB_ST_REQUEST_ERROR -ENXIO a control or interrupt URB is already queued to this endpoint; or a bulk URB is already queued to this endpoint and USB_QUEUE_BULK wasn't used (UHCI HCDs only) USB_ST_URB_INVALID_ERROR -EINVAL a) Invalid transfer type specified (or not supported) b) Invalid interrupt interval (0<=n<256) c) more than one interrupt packet requested d) ISO: number_of_packets is < 0 -EAGAIN a) specified ISO start frame too early b) (using ISO-ASAP) too much scheduled for the future wait some time and try again. -EFBIG too much ISO frames requested (currently uhci>900) USB_ST_STALL -EPIPE specified pipe-handle is already stalled -EMSGSIZE endpoint message size is zero, do interface/alternate setting USB_ST_BANDWIDTH_ERROR -ENOSPC The host controller's bandwidth is already consumed and this request would push it past its allowed limit. -ESHUTDOWN The host controller has been disabled due to some problem that could not be worked around. ************************************************************************** * Error codes returned by in urb->status * * or in iso_frame_desc[n].status (for ISO) * ************************************************************************** USB_ST_NOERROR 0 Transfer completed successfully USB_ST_URB_KILLED -ENOENT URB was canceled by usb_unlink_urb USB_ST_URB_PENDING -EINPROGRESS URB still pending, no results yet (actually no error until now;-) USB_ST_BITSTUFF USB_ST_INTERNALERROR -EPROTO a) bitstuff error b) unknown USB error USB_ST_CRC -EILSEQ CRC mismatch USB_ST_STALL -EPIPE endpoint stalled USB_ST_BUFFEROVERRUN -ECOMM During an IN transfer, the host controller received data from an endpoint faster than it could be written to system memory USB_ST_BUFFERUNDERRUN -ENOSR During an OUT transfer, the host controller could not retrieve data from system memory fast enough to keep up with the USB data rate USB_ST_DATAOVERRUN -EOVERFLOW The amount of data returned by the endpoint was greater than either the max packet size of the endpoint or the remaining buffer size. "Babble". USB_ST_DATAUNDERRUN -EREMOTEIO The endpoint returned less than max packet size and that amount did not fill the specified buffer USB_ST_NORESPONSE USB_ST_TIMEOUT -ETIMEDOUT transfer timed out, NAK USB_ST_REMOVED -ENODEV device was removed USB_ST_SHORT_PACKET -EREMOTEIO short packet detected USB_ST_PARTIAL_ERROR -EXDEV ISO transfer only partially completed look at individual frame status for details USB_ST_URB_INVALID_ERROR -EINVAL ISO madness, if this happens: Log off and go home -ECONNRESET the URB is being unlinked asynchronously ************************************************************************** * Error codes returned by usbcore-functions * * (expect also other submit and transfer status codes) * ************************************************************************** usb_register(): -EINVAL error during registering new driver usb_get_*/usb_set_*(): All USB errors (submit/status) can occurDownload Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
