Hi,<br>
<br>
IOERROR usually means an electrical error. The RPI3B will use a <br>
transaction translator for the FULL speed traffic, which is driven by <br>
software. Maybe there is a bug in the HC driver, <br>
"dev/usb/controller/dwc_otg.c". There are some sysctls to enable =
full HC <br>
debugging, see hw.usb.xxx.debug=3D17 .<br>
<br>
Is the device self-powered?<br>=C2=A0 <br></blockquote><blockquote class=3D=
