Shamelessly cross-posting from the Keil forum:

I'm in the UK, using the Keil C51 toolset, and the Triscend E5.

Being in Europe (or, should I say, outside the USA?) I have to use a "dongle" (hardware key) with the Keil tools.

Far from being transparent, the Keil dongle seems to significantly mess-up the communication bewteen the parallel port and the Triscend JTAG.

Keil's knowledge base article http://www.keil.com/support/docs/1788.htm suggests that this may not be an uncommon experience.

Has anyone else experienced problems with the Keil dongle - particularly in connection with the Triscend E5?

Any tips?

PS
I should be grateful if contributors would confine themselves to actual issues with actual dongles; if anyone wants to start a separate thread on the general philosophies of dongles, software protection, etc then please feel free - but please make it a separate thread!
