[fpc-pascal] USB Human Interface Devices

[Johann Glaser]

Hi Jean!

Thanks for your effort and please excuse my late reply, I was busy the
last few days.

Please note that for pas-libusb there is a dedicated Git branch for the
newer LibUSB 1.0. The branch is called "libusb-1.0". Marc pointed to
that in his EMail from Fri, 26 Jul 2019 15:56:17 +0200.

I'm sorry for the confusion! I've now updated the Readme.rst in the
branch "master" to point that out.

In the branch "libusb-1.0" I've lately changed a few things (see my
EMail from Tue, 30 Jul 2019 22:54:07 +0200) so that all dependencies to
Linux units should be gone.

Actually, with the branch "libusb-1.0" you should not need any "compat"
stuff any more.

Could you please give that a try and see whether you are more
successful with it?

Regarding "lsusb": The "test1library.pas" example should be just that.

Regarding the testfirmware example: This is specifically for devices
with the EZUSB Chip (e.g., Cypress AN2131). It is included to
demonstrate, how you could implement your own interface to your own
device with other chips with SRAM firmware (e.g. Cypress FX2 or FX3).

Bye
  Hansi
