Re: [Libusbx-devel] [libusbx] break from never ending loop. fix #76. (#167)

[daves0 <not...@gi...>]

Here we are almost a year later, and the "not-found" error return from libusb_cancel_transfer is not being handled.  It appears efforts here were stopped because one person can cause this problem in a manner that also involves EFAULTs.  In the end, however, there's still a looping bug in libusb, is there not?

The loop can only be exited when a specific condition occurs / state is reached.  There is a function call within the loop that can return a "not-found" value that indicates that the desired completion state will never be achieved.  This return value is ignored.  Sounds like a bug to me, no?

Can someone please correctly handle the failure (not-found) return from libusb_cancel_transfer that's inside of sync_transfer_wait_for_completion in a manner such that the endless loop doesn't occur any more?

Thanks!

Dave
