Whenever I plug in my NJB and trasfer files to it it
works fine the first time around (i've modified
sendtr.c to allow me to send multiple tracks). When the
program exits and sends NJB_Release(njb); etc I can't
upload again without getting a message reading..

usb_bulk_read: Connection timed out
njb_ping: I/O failure on USB data pipe

If, however, I unplug the NJB and then plug it in
again straight away the program works fine, no error
message (until I forget to unplug again!).

I'm using libusb 1.4, Kernel 2.4.14 and the latest cvs
fetch of libnjb. Any ideas? Patches? Easy fixes?

    This is a known issue, and it seems to be a problem with
    libusb or the Linux implementation of user-level USB, and
    not libnjb itself. Other than unplugging/replugging, I know
    of no sure-fire ways to solve the problem.

    I believe this is a problem from the past...
