uaEFI + uaDASH + dash sweep script we get CAN TX failure on simultaneous power up

[rusefillc]

uaefi with dash-sweep.lua script
uaDASH7
lab power supply
no USB

power on

actual result: no activity on dash

if we hook USB and connect with TS, we see CAN TX ERR going up on ECU side

[rusefillc]

workaround:

power up uaEFI first

power up uaEFI later

result: sweep works!
