qemu? qemu+kqemu (the kernel module)? kvm? I would expect plain qemu to
have pretty bad performance, though I hardly tried to use it lately.

Anyway, it should be more than enough for the simple firmware loading
step.

That's good.

Technically the Astribank driver requires USB 2.0 as it was not worth it
to adapt it to the maximal URB (messagee) size of 64 byte of USB 1.1.
astribank_hexload actually was never adapted to that limitation either.
While this may be considered a bug, we hardly needed to load the
firmware on USB 1.1 and this gets an earlier and safer fail on most
cases.

Anyway, astribank_tool does not use large USB messages. I would not
expect it to fail on USB 1.1 . The problem is elsewhere. What happens if
you manually run:

  /usr/share/dahdi/xpp_fxloader load #?

Or:

  astribank_tool -D 001/005 -Q

If you have dahdi-tools < 2.5, you'll need:

  astribank_tool -D /dev/bun/usb/001/005 -Q

What version of dahdi-tools is it?
