Hello world,
as I have read on the QNX Supported Hardware Page, there are two
usb-drivers available, the devu-uhci and the devu-ohci. My question is,
what is the difference between the two? The page does not say anything
about the chipset they support, as it is the case on other Supported HW,
eg. the sound chip ess-solo. As I have leared from the news group the
thing to do is start both of the drivers and see which one will work on
a spezific machine.

Thanks for any comment
Norbert
