[walac]

Implement device add/removal events for PyUSB.

I saw that issue: https://github.com/walac/pyusb/issues/22
Is there already a hotplug event notification support for pyusb?

[walac]

Not, it doesn't.

FYI: I am working on this.

@walac the hotplug callback returns a libusb_device. Where and to which type should it be converted? Should my hotplug implementation to the conversion to Device(_Device(dev, backend))?

[walac]

@roberthartung Sorry for the delay, crazy work days. Thank you for working on this, as you already opened a PR, I will discuss design there. I will review it soon. Thanks again.

[roberthartung]

@walac great! Let me know what you think about the design and I can make changes and make a new pull request if necessary!

[roberthartung]

@walac Any news on this?

[walac]

@roberthartung I am really sorry for the delay, but I am quite busy in work and personal stuff and could not give PyUSB the love it deserves so far in this year. I hope getting back to it soon.

[roberthartung]

Just uploaded a fix for user_data. See #160

[leileigong]

how pyUSB hotplug is going？

[roberthartung]

@leileigong Just merge PR #160 into your fork/branch. It works :-)

@mcuee I don't see why this issue needs to be pinned.

[mcuee]

I agree. Just unpin it.
