Atmel USBA Device Driver

This is the driver for the Atmel USBA USB Device Controller, which can be found integrated on AT32AP700x chips. It works well with the g_file_storage and g_ether gadgets together with both Linux and Windows hosts. Other gadgets should work as well, but they haven't been extensively tested.

Features

  • USB 2.0 High-speed capable
  • USB 2.0 Test Mode
  • DMA is used for all transfers except control endpoints
  • Supports up to 7 endpoints (control, bulk, interrupt)
  • Supports Vbus sensing if the board supports it (STK1000 does not but can be hacked)

Known issues

  • Isochronous endpoints are supported by core but not tested with the driver. Probably doesn't work.
  • usbtest shows spurious failures with control transfers.
  • REMOTE_WAKEUP feature is not handled. SET and CLEAR requests are successful but ignored.
