topic HID USB Communication Failing after exactly 31 sends. in MQX Software Solutions https://community.nxp.com/t5/MQX-Software-Solutions/HID-USB-Communication-Failing-after-exactly-31-sends/m-p/243004#M6879 <HTML><HEAD></HEAD><BODY><P>I'm using MQX 4.0 and I'm having an issue with the USB HID communication trying to send data. My HID layout is a modification of the HID Class driver that's built in, different only that I also need to read data were as the base HID class doesn't perform that. What my issue is, is that when I send data from my hardware (K60F120) after exactly 31 transactions I get an error from the USB_Class_Send_Data() which is transfer in progress. I was told to use the _usb_device_free_XD() but I can't find any documentation on how I'm suppose to use. I'm hoping someone might know of a solution to this.</P><P></P><P>Thanks in advance.</P></BODY></HTML> Wed, 07 Aug 2013 01:00:45 GMT Dealerz 2013-08-07T01:00:45Z HID USB Communication Failing after exactly 31 sends. https://community.nxp.com/t5/MQX-Software-Solutions/HID-USB-Communication-Failing-after-exactly-31-sends/m-p/243004#M6879 <HTML><HEAD></HEAD><BODY><P>I'm using MQX 4.0 and I'm having an issue with the USB HID communication trying to send data.

When I make the call to USB_Class_Send_Data() I get and error code of 0x03 (USB_STATUS_TRANSFER_IN_PROGRESS). I was told I had to call _usb_device_free_XD() but wasn't given a place on where or how to make this function call. This happens on the 31st transmission. How do I resolve this, has anybody else ever seen this?</P></BODY></HTML> Mon, 09 Sep 2013 22:13:33 GMT https://community.nxp.com/t5/MQX-Software-Solutions/HID-USB-Communication-Failing-after-exactly-31-sends/m-p/243005#M6880 Dealerz 2013-09-09T22:13:33Z
