[Bitpim-devel] libusb / Darwin

[Steven P. <n9...@n9...>]

Hi Roger,

I am still working on the libusb issue... I thought I'd see if you had 
any insight on this one.

Here is what I get as a dump from `python usb.py` (relevant section to 
the VX6000 only):

usb_os_open: 0410:0060
usb_os_open: device opened
usb_control_msg: 128 6 512 0 0xbffff568 8 1000
usb_control_msg: 128 6 512 0 0x510e60 90 1000
skipped 4 class/vendor specific interface descriptors
usb_os_close: 0410:0060

I've managed to stop the system (for now) from loading it's own device 
driver on the port, and therefore allowing libusb to access it. 
Eventually, I will want to have the workaround in place so both can 
co-exist, but for troubleshooting this may be easier.

I'm just perplexed as to why libusb is skipping the interfaces on the 
device. Here is a dump from libusb's `testlibusb` application:

Does this look normal to you, or is something not quite right in the 
base darwin libusb stuff?

Thanks,
