[Legousb-devel] LEGO USB Tower driver 0.7 for Linux 2.6

[Juergen S. <st...@lo...>]

Hi everybody,

attached is a new version of the driver that works nicely for me
and corrects some problems of the old version, in particular
the sleeping in interrupt context due to incorrect semaphore use.

I tested it with with Lejos and nqc-3.0a2 on x86 machines with
both UHCI and OHCI host adapters, and it works very well for
firmware, program and datalog down- or upload.  NQC needed
a small patch due to compilation issues, which is also attached.

As for proper EHCI over a USB 2.0 hub, that fails with a -ENOSPC
on the submit of the first interrupt read URB.  This needs
to be investigated, but I suspect it is a problem in ehci-hcd,
which is said to still have problems in this area.

I would be grateful if somebody with a different architecture
could test it, especially for big-endian and/or 64 bit.

When all is well I'll submit a patch for the kernel.


Have fun
