Hi, thank you for maintaining uhubctl, I use it all the time!

I was wondering if BIG7: 7-Port MTT USB Hub for Raspberry Pi (Rev 2) would work with uhubctl?

Thank you

I have no idea. Most devices in supported table were reported by users like you. Please check and report! 🤣

Actually, I looked deeper at specs, and I believe it will NOT work. It was created by @uugear - same vendor who created MEGA4 (which is fully compatible with uhubctl).

Per their documentation:

...the power of USB ports could be controlled by software or external switch (note: it is not Per-Port Power Switching (PPPS), please read the [user manual](http://www.uugear.com/doc/BIG7_Rev2_UserManual.pdf) to learn how it works).

Crucial part is it is NOT Per-Port Power Switching. So answer is no.

Ah, I was about to order one to run some tests when I saw your answer. That's a shame, I like MEGA4 but it would be really nice to have more channels. Thank you for checking!
