I am trying to implement a USB 2.0 host for a custom class on a CYW54907 wireless SoC (CYW943907AEVAL1F dev board). I would like to connect the host to a custom class on a USB device running on an FX3 module (CYUSB3KIT-003 EZ-USB® FX3™ SuperSpeed Explorer Kit).
I am using USBX dpump to create a custom class on the host (see attached code). I also added dpump to the event handler in wiced_usb.c (attached). On the FX3 device, I am running the default BulkLoopAutoCpp example. I have also tried running the MouseDemo on FX3.
I cannot get the custom DPUMP class to work. I notice that when I plug the device in, the event callback function (wiced_usb_host_usbx_host_evt_callback) in wiced_usb.c does not trigger. I suspect the reason is that the UX_HOST_CLASS class instance NULL? I get the same result when I test with default USBBulkSourceSinkLED example on FX3 (the LED doesn't even light up). Here is the terminal debug terminal output from this test:
+-------------------------------------------------+

loopback

*** Please input any key from your terminal program ***
DPUMP == NULL
---END: DPUMP test
I also checked the MouseDemo with the same host – it enumerates as an HID device, and successfully executes the event callback function (see red). (It also prints data successfully when run with hid_keyboard host app). Here is the terminal output:

Could you please assist me in getting a custom class to work?
Many thanks in advance.
Hi,
We too noticed a issue with USBX DPUMP class and are checking with expresslogic currently., I will update you on further developments.

Thanks. In the mean time, are there any other code examples for transferring raw data over two bulk endpoints that I could use? I need high speed, so do not want to use a virtual COM port.
I have meet the same issue, do you have any progress? thanks.
Madhu Lakshmipathy confirmed the issue 8 months ago.
I notice now it usually takes very long time to get bug fixes of the sdk, this is not good.
