Alchitry Labs can flash boards but Alchitry Loader cannot
#1
I can use Alchitry Labs to edit files, create the bitstream and flash the boards. However, when I use Vivado to edit files and then generate the bitstream then use the Alchitry Loader to load the bit file, I cannot.

When I use the command line tool with argument "-l" I get the following output:

Devices:
    0: Unkown
    1: Unkown

I get this output when I put the board in any USB port and if I use the Au or Cu boards.

"lsusb" command shows the UART chip on the board is being detected by the computer with the correct name (FT2232C/D/H, which indicates the FT2232HQ chip which is labeled as U5 on the 4th page in the Cu schematic found here: https://cdn.shopify.com/s/files/1/2702/8...cu_sch.pdf and on page 5 in the Au schematic found here: https://cdn.shopify.com/s/files/1/2702/8...au_sch.pdf).

I have already copy and pasted the 99-alchitry.rules file into /etc/udev/rules.d as detailed in the instructions found here: https://alchitry.com/pages/alchitry-loader

I use Debian 10, a Linux distribution.

Any help and/or guidance would be greatly appreciated.
