On my devices the vendor id is the same, so the plugdev file should be universal.
Did you have success on frequencies above 850 MHz?
I noticed you put a voltage section in the configuration, that sets some voltage on gpio5
Is this documented somewhere else ? I looked in the datasheet but couldn't find anything there, neither in the gridseed cgminer version on github.
Where did you find this additional information ?
For now it's running stable on my pi @850MHz for 3 hours and my pi is clocked at default frequency.

Look for vid0 and vid1. By default vid0 is low, but unfortunately setting it high reduces the voltage. It's possible to bridge solder ovd33 to vid1 (low by default), but that might also lower the voltage. If you were really adventurous, I think you could attempt to replace resistor R139 (27k) with one of slightly lower resistance. I'm finding 850 MHz to be a good choice.
