Hi Garratt,
sorry for causing confusion. My libusb wrapper code has separate
readControl and writeControl functions because I dislike the idea of
using a bit flag to switch between read and write in libusb. As a side
effect, my readControl function sets bit 7 on the read mask itself to
make it transparent to the user; in other words, when I call
readControl(0x40,...) libusb actually sees 0xC0 for the first parameter.
So my code is in line with the other code you reference.
I obviously should have documented that better.
I know that my accelerometer code works otherwise; I've played around
with them for a bit.
Oliver
