For the initial submission, I'm hoping to include device drivers for USB and serial support. The first 20 or so patches are ready for review, with 5-10 additional patches needing clean-ups. USB maintainer Alan Stern has previewed the PS2 OHCI driver: https://marc.info/?l=linux-usb&m=151198476018400 Simple devices such as a USB keyboard work. Jürgen Urban has reported issues with USB mass storage devices, possibly due to lost interrupts. I tried a wireless AR9271 USB device. It had at least two problems: First error was "ath9k_htc: Unable to allocate URBs", due to the (very) limited amount of reserved IOP memory (256 kb). I then adjusted a few hardcoded ath9k_htc buffer limits. The following error was "ath9k_htc: Target is unresponsive" which remains to investigate. Jürgen: In ps2_uart.c for v4.15, the init_timer call needs to be replaced with timer_setup. Work in progress: https://github.com/frno7/linux/tree/ps2-v4.15-n0 Fredrik
