Doesn't exit (libusb problem?)

[krissen]

Seems antfs-cli doesn't exit properly, even though it's done.

I get this:

Driver available: [<class 'ant.base.driver.USB2Driver'>, <class 'ant.base.driver.USB3Driver'>]

libusb: warning [libusb_close] internal signalling write failed, closing anyway

Emphasis being on the last line. Stalls there. I get that this might be libusb's issue, not antfs-cli, but do you have any idea what might be done to fix it?

[Tigge]

I haven't seen that error before. What version of libusb are you using?

[krissen]

1.0.19

[Tigge]

What about pyusb?

[Tigge]

Probably this issue I think: https://github.com/walac/pyusb/issues/66.

[krissen]

pyusb-1.0.0b2.

OK; thanks. I'll check into walac/pyusb#66. As with the reporter @ walac/pyusb#66, I'm also on python 3.4. So looks probable.

[krissen]

If I understood it correctly, the patch fixing walac/pyusb#66 had been merged into walac/pyusb master, but I'm having the same issue even though having built and installed the latter.

[Tigge]

Hm yes, that is weird. if you run python and do:

import usb
usb.__version__

That is the correct version? If it is finding the correct pyusb installation and this still occurs, I'm afraid I have no idea what is wrong.

>>> usb.__version__

Trying to see if I might get help from project walac/pyusb.

[krissen]

@walac asked for a test script to reproduce the issue (over at pyusb#66). I haven't dabbled in Python before, so instead of trying to scrape your code for tidbits which might make up a test script reproducing this issue, I'll ask you first. Would it be possible for you @Tigge to make some minimal script which should(n't) lead to the error message above @ comment 61684472?

[Tigge]

I think you are using the version built from master you should have version 1.0.0.rc1 of pyusb I think. Perhaps you have a conflict between a version installed by your package manager and the one you installed manually (or with pip or so)?

[krissen]

I had none installed through package manager (portage). When trying to fix this, I installed something that looked related through pip. Removed that now.

But, alas,
