Prolific PL-2303 driver 2.0.2.1 causes crashes

Version 2.0.2.1 of the Prolific PL-2303 USB serial port driver is buggy. It caused an IRQL_NOT_LESS_OR_EQUAL (0x1000000a) crash twice, both times when I was sending a file to a serial port via copy in cmd and I aborted the copy with Control-C. Windows fails to find an updated driver, but a much newer driver can be downloaded from Prolific. I'm now using version 3.3.11.152, which seems stable so far. This is in 32 bit Windows 7.

Hahaha, that was wishful thinking. They only addressed some BSOD issues several versions later, in 3.4.25.218 and 3.4.31.231.

I'm hoping that the August 2012 (1.7.0 driver package) will stop the crashes.
