MAX3421E on bf527

Question

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

I am afraid you can get more information by asking the vendor Maxim, we have no implementation of this chip.

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.
