Can anyone recommend any good USB controller ICs? I normally just use a microcontroller with USB built in.
- lemonlime0x3C33 2y agoI have had a good experience using microchips USB2514 and USB2512
- stragies 2y agoI just looked up the USB2514, and it would seem to not support PerPortPowerSwitching. (used by e.g. uhubctrl to toggle/switch power to individual USB ports). Am I not reading the specs correctly?
- lemonlime0x3C33 2y agoI was able to reset downstream USB devices using usbreset to the individual ports (or the entire hub) in my design, using usbreset. I did also have a hardware reset built in using the cfg_sel0 and cfg_sel1 pins 24 & 25 and RESET_N. I did not try to turn off power to those ports for any extended time so I am not sure if that works.
