Driver for external usb controller
I am trying to write a driver for a USB controller chip, model is ISP1761 by NXP, host is a a PQ2, QNX version is 6.3.2.
My driver code is accessible to io-usb via a table of type "io_usb_dll_entry_t". However when I run io-usb and specify
the library I created in the command line, nothing happens. I never see it enter my functions, etc. Anyone know if my
init function, found in the table, is supposed to get invoked on being loaded? Is this table the correct one that io-
usb uses to invoke functions in the driver code?
Command:
io-usb -disp176x verbose=5,irq=2 -vvvvv
Thanks.
P.S. If anyone wants to take over this task, I may be able to offer them some consulting work.
