Opentx Companion 2.3.5 Jumper T16 can read SD card

[dtunstill]

I have a new Jumper T16 that shipped with OTX 2.3.2. I downloaded OTX 2.3.5 using Companion 2.3.5. Everything on the radio seems to work, I can create models, read the SD card and delete models that are stored on the card.
When I try to read models from the radio in companion it gives a no sd card found. I have reset the ribbon cable going to the card reader and tried different cards and usb cables.

Would the card reader be bad? Any other ideas?

Thanks

The radio uses the card for everything so if it works the card and reader are OK. Probably bad or charge-only USB cable.

How are you connecting your radio ? turned on ? off ? bootloader?

I have tried connecting turned off, it will not read anything from sd card in companion.
If I connect with the radio turned on in bootloader mode, I can see the sd card as a drive on the computer, but can not write anything to it.

@Kilrah Thanks, you got me looking at USB cable again, I tried two other cables they didn't work either.
@3djc I went back and retried radio off, radio on and bootloader still no luck.

THEN I did what I should have done in the first place, I uninstalled and reinstalled companion used ImpulseRC driver fixer and
IT WORKED ...
Thanks guys for getting me started in the right direction.

SD card access needs radio in bootloader, can't do that when off...
