USB Host i.Mx6S

Hi everyone

did anyone get a USB Stick Mass Storage to run, connected to i.MX6 Solo USB H1? I can get it running on OTG Pure Host, but not on USB H1. It runs into a timeout on issuieng GetDescriptor during usb_rescan. 

Using a scope i don't see any traffic on D+/D-, what i observe is a drop of D- to 1.3V where i expect 3.3V, which i see on Connection to USB OTG (USB stick is a low Speed device, therefore D- High).

Any ideas? Is there an additional Setting for UTMI/USBPhy required?


Mit freundlichen Grüßen aus Berg/ With kind regards
