As I promised, I've tried usbsnoop on the Windows driver last weekend.
This is the updated list of _string_ descriptors (type = 3) to use:

0x3	Q1
0x4	T
0x5	TL
0x6	T<n>	(don't know how to pass the parameter)
0x7	Q
0xb	CT
0xc	I
0xd	F
0x68 and 0x69 both cause shutdown after an undefined interval :)

These are results of reverse-engineering, my own UPS doesn't
perform all things right. For example, T* commands make it doing
test but only for 1-2 seconds. Shutdown time varies from 17 to 40
seconds.

I've solved also the majority of problems I had earlier, I'll write
about these issues a bit later, since the solutions could vary.
