Invalid USB EP length

Postby kilaueabart » Sat Jan 20, 2018 9:55 pm

I resolved sound problems in my Ubuntu by adding a USB sound card. It works great, I can watch videos, play my audio collection just fine now.

But if I have that USB card plugged in when I boot Ubuntu, U-Boot complains about an "invalid USB EP length" with a 9 I think in parentheses. I haven't been able to find out what that means, except that it apparently means something has run afoul of this command:
Code: Select all
case USB_DT_ENDPOINT:
         if (head->bLength != USB_DT_ENDPOINT_SIZE) {
            printf("ERROR: Invalid USB EP length (%d)\n",
               head->bLength);
            break;

Should I be concerned about this and learn how to fix it? The boot proceeds as expected, and I detect no problems on the computer thereafter.
