I’m using WP76xx modules on a custom board and am having trouble with WP7605 variant, specifically with instrumenting USB peripherals. More specifically,
/sys/bus/platform/drivers/msm_hsic_host doesn’t exist.
Using the same firmware and target hardware with WP7607 and WP7610 doesn’t cause the problem and has happened on all WP7605 modules so far.
Are there any known issues or differences to the module?
Edit: Going through dmesg this may shed some light
