DSO-2090 USB - EXT and EXT/10 trigger not working. #321

Openhantek 30.10.2020_e7e0ec7b built on 64bit Debian with DSO-2090 USB.

No triggering happened after first shot when set to EXT or EXT/10 with EXT connected together with CH1 to 2Vpp 1K test outlet.

EXT and EXT/10 work as expected on stock win10 and XP hantek exec. BTW, the stock has an extra trigger setting of ALT (alternating between CHI and CH2).

Same issue seen on pulseview over sigrok.

It turns out to be same as #285. I got some triggering on EXT by setting specification.specialTriggerChannels to -1. OK for now, Other minus settings beyond -3 seem working too. However I cannot really tell which is EXT/10 until I have an adjustable trigger source. It is likely a modelling issue as sigrok has the same problem.
