Re: [OpenOCD-user] FTDI and ST-Link V2 problems with OpenOCD 0.11.0 on Windows

[Tarek B. <tar...@gm...>]

this reminds me of an old issue with Windows 7 and some USB 3.0 controllers
(like NEC/Renesas)
upgrading the controller driver may solve the issue (please see
https://github.com/libusb/libusb/wiki/Windows#USB_3x_Support )

I have used the package pointed out by Xiaofan without issues on WIN 10, I
can't check on WIN7 before next week.
By the way this package is not 64-bit, it's compiled for 32-bit, and should
be OK on 64-bit (my case for example).
