Closed goldendeng closed 6 years ago

goldendeng commented 8 years ago

In the Windows 32 system, unplug USB hub when transferring files , will cause the spicy.exe block for two minutes, I found usbdk obstruction and attempted to do the modifications, can solve the problem.

Does this problem exist when working with UsbDk 1.0.15?

goldendeng commented 8 years ago

This problem exist when working with UsbDk 1.0.15,and if WaitForDetachment() timeout ,device still not detached.I think, set the timeout period seems to have little effect.

dmitryfleytman commented 7 years ago

Do you have any idea why is it stuck in the first place, i.e. why WaitForDetachment() times out?

so I think mabey usb-device-manager should disconnecting device first can avoid this problem.but I can't find a way to control.
