[hpsdr] ghpsdr question (ozy_ep4_io_thread: OzyBulkRead failed)

[John Melton]

Hi Richard,

You should be using the latest libusb1.0 (which it looks like you are).

All you should need to do is run initozy and then run ghpsdr.

If you do not see EP4 have you updated Mercury to v2.6 and secondly have 
updated to use the latest Ozy_Janus.rbf and ozyfw-sdr1k.hex?

After running initozy run the command:

  lsusb -v -d fffe:0007

You should see EP2, EP6 and EP4 defined. The output on my system looks 
like below.

Regards,

John g0orx/n6lyt
