[Pcsclite-muscle] further issues with O2MICRO OZ776 (0b97:7772)

[Stephan Bärwolf]

Hi all.

Recently I was confronted with serious issues regarding the reader within Fujitsu Lifebook E754.
Turns out it is the O2 Micros's OZ776.

Simplified: I was not able to read back some x509 certificates with it. (And other security tools errored while using it.)
(Althought all test passed using an external USB card reader...)
After debugging it more and more became obvious, all disruptions are caused by an LIBUSB_ERROR_TIMEOUT (-7) - the reader simply didn't respond in some cases.

Hereby I want to suggest my patch making the reader fully usable.
In case somebody needs pcscd before-patch- and after-patch logs, please write me, I will make them available then.
