  1. Hi, First time user here. I'm using the legacy Jessie build with kernel 3.4.109 Kernel. OTG is enabled and generally working. However, with some USB devices we are getting the following message with dmesg: WRN:L2705(drivers/usb/sunxi_usb/hcd/core/sw_hcd_host.c):ERR: sw_hcd_schedule, best_end [ 663.633167] WRN:L2951(drivers/usb/sunxi_usb/hcd/core/sw_hcd_host.c):ERR: sw_hcd_schedule failed [ 663.641968] cannot submit datapipe for urb 0, error -28: not enough bandwidth This only happens with some USB devices. My USB headphones work fine but a USB DAC for music does not. I remember reading somewhere the OTG on the BananaPi seemed limited in terms of actual connection speeds. Are there any specific restrictions on the OTG? Any ideas how to solve the issue? Thanks, Nuno
