MAX3421E on bf527

Has anyone tried to implement the MAX3421E spi/usb chip?  So far I cannot find even a generic driver reference.

  • Sorry for late answer to old question, but the mainline linux kernel has a usb host driver max3421-hcd (under drivers/usb/host). May require editing configuration file to enable building the kernel module and configuring system device tree to specify which spi port / interrupt port are connected to the hardware. I have recently had success compiling this driver under kernel 6.1.y on Raspberry Pi OS.
