Benjamin-Dobell commented (re the general thread there) “Hmm. it couldn’t open /dev/bus/usb/001/050, due to a general IO error, which unfortunately isn’t very specific, and is quite odd. It’s not a permission issue, because there’s a separate error code for that.
I did some quick digging through libusb and for this error message to occur POSIX open() is setting errno to EIO, which is unfortunately a general error. However, under normal circumstances, realistically it shouldn’t occur, you should get a more specific error. This makes me think that there is a driver bug, or some kind of hardware failure on your system - but it’s hard to tell with such a generic error.”
- [Solved] Try a different cable! The caller told us he had been using the Samsung cable that came with the device, a replacement allowed Easy Installer to complete.
What does this tell us?
Perhaps everyone planning to flash a phone should blow all their USB ports out with compressed air.
Throw away any USB cables with slack connection.
Throw away any twisted usb cables. The only good reason to wind a wire is to create an Electromagnetic force.
