如果带宽不足以支持启用接口内的时序、控制和中断终结点,则选择配置请求和选择接口请求可能会失败。 在这种情况下,USB 总线驱动程序会将 URB 标头的Status成员设置为 USBD_STATUS_NO_BANDWIDTH。 以下示例代码显示了如何创建USBD_INTERFACE_LIST_ENTRY结构数组并调用USBD_SelectConfigUrbAllocateAndBuild。 该示例...

It seems that the error is due to insufficient USB bandwidth or too slow speed, but no reliable solution has been discussed. For your reference: https://lore.kernel.org/linux-usb/CAJ+vNU194rZZRjQxSjN6OXXWBEgniHcO1=g==rPwcumKqhh1hA@mail.gmail.com/ One more question, do you have ...
