To reiterate: we do not have a driver for TI 5052 chips. It's not much like other usb-serial chips. In fact it's not strictly a usb-serial chip, it's a multifunction chip that includes a software -controllable usb hub, 2 serial ports, gpio, an i2c bus master, an MCU interface, a multichannel DMA controller, and apparently even has the ability to download your own 8052-compatible microcontroller code into the 5052 and have it take over from the built-in rom code. It would be reasonable enough to write a driver that initially supported only the uart part of the chip. -- Ian _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
