download-env.sh fails due to liteusb

[lachlansmith]

Hi the download environment script never goes as far as installing the litex suite because it fails to clone liteusb. Is liteusb no longer a thing? I'm getting a 404 from https://github.com/enjoy-digital/liteusb.git/ is this just me?

Same

Should be fixed by https://github.com/timvideos/litex-buildenv/pull/754 - can people verify?

I ran this curl -fsS https://raw.githubusercontent.com/timvideos/litex-buildenv/master/scripts/bootstrap.sh | bash and the third_party stuff seems to work, but then it fails as below. Looking at why. Seems like it thinks I'm on windows not linux.

Ok, this has to do with me being on an M1. I get further with the following patch

I tested it on linux x86 and it installs fine.
