Title:
  Read certificate from USB key failed

Status in QEMU:
  Expired

Bug description:
  QEMU release version: qemu-2.9.0
  VM operation system: win7 32bit

  I have an usb key which can be redirected and recognized in VM.
  However, it is failed to get the certificate when using the official
  application for this usb key. What's more, the whole app is stalled
  untill this usb key detached from VM.

  As I researched, this usb key uses interrupt transfers when
  application trying to read certificate from it. Problem is that some
  certificate data abandoned by "usbredir_stop_interrupt_receiving" and
  "usbredir_stop_ep". The two functions use "usbredir_free_bufpq" to
  clear the buffered usb packets, even the certificate remain in the
  bufpq.
