Hi! I've googled: "usb" "designware" "otg" "datasheet"
I think this is the kernel driver for this device: https://github.com/torvalds/linux/tree/master/drivers/usb/dwc3 Maybe it should be possible to use this as a reference? Maybe try to redirect the proprietary drivers system calls? I don't know... I've also found theses docs, which explains the device a little bit: http://www.infradead.org/~mchehab/kernel_docs_pdf/driver-api.pdf https://media.digikey.com/pdf/Data%20Sheets/Austriamicrosystems%20PDFs/AS3524.pdf https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/arria-10/a10_54018.pdf Thanks. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1772165 Title: arm raspi2/raspi3 emulation has no USB support Status in QEMU: Confirmed Bug description: Using Qemu 2.12.0 on ArchLinux.
