Hi,

   My customer--Fujian Landi want to use low speed USB device for K21, now USB can't work well. i tried the customer's problem,  I pull up 1.5K resistor in D-, and run KSDK1.2.0 USB HID device example in TWR-K21D50M,PC can't recognize the device. I read the K21DN512 RM, and found RM only mention OTG supports FS device. K21DN512 can support LOW SPEED device? and How to run LOW SPEED USB examples? Thanks.

 

Best Regards,

Fred Fu
