Re: [Pyusb-users] Problem with using pyusb in snow leopard

[Wander L. <wan...@gm...>]

Hi Joe,

It feels like this error comes from libusb. Moreover, it feels like a
deployment issue, try to install libusb 0.1 from sources. If it
doesn't work, try to backtrack a few libusb minor version and try
again. Whatever, it is maybe a good to report your problem to libusb
mailing list. If you know a bit of C language, you could try to write
a little program que calls usb_bulk_read, just to see if the system
can resolv the symbol...
