USB host doesn't seem to be working on letux-5.6.y at all. Neither the LTE module nor any devices connected to the host ports or an OTG adapter are detected in lsusb. The SMC hub (0424:3503) sometimes shows up in lsusb and sometimes doesn't, with little discernible pattern. Weirdly, USB works perfectly on the uEVM which even seems to use the same HSIC hub IC, just slightly different power arrangements...

Was a reset polarity issue: https://pyra-handheld.com/pipermail/kernel/2020-July/004374.html Not sure why it also affected OTG, but that is working too now. As is the modem (and the modem taking 255 seconds to appear on PyraOS bug seems to be fixed too in 5.6.y).
