What you call “root hub” is for me simply a “root port” which does not has the function of a standard USB 2. I went though hell while developing for it. And as far as the control endpoint 0 packet size.. I favored u-boot because I’ve used it for other projects. For technical support please post your questions at http: A better use for this is, if you know the register name you’re looking for, by using grep we can reduce the amount of output. It seems too small.

Wed Dec 04, 8: This page was last modified on linxu Aprilat Now I’m able to enumerate those devices. Note the two directories terminated with. Shows current USB 2. The following diagram depicts dwc3 integration in AMx.
Nothing like replacing one bug with another. Both of those directories contain the same thing, we will use It sure would be nice if Synopsis made their documentation of the DWC available.
Look at what I told you before: And as far as the control endpoint 0 packet size. Thu Dec 12, You will need a mini-A to Type-A adapter to use the Host port. The USB0 host port has a standard A female so no special cables needed.

The following diagram depicts dwc3 integration in OMAP5. Cheers and apologies for the long og Select all Get first 8 bytes of device descriptor to get max packet size Get complete device descriptor Set device address to 1 Get configuration descriptor without trailing interface and endpoint descriptors to get wTotalLength Get full configuration descriptor wTotalLength Set configuration to bConfigurationValue Get hub descriptor Enumerate downstream ports see dwd posting about getting port speed.
Ilnux Dec 04, 4: Because the project I am involved in requires to use an external USB hub Cypress HX3 based for various input devices, I had the chance to observe quite a few issues with for example one or more USB keyboards and a touchscreen controller USB plugged in at the same time.

USB (DWC) Enumeration ? – Raspberry Pi Forums
Wed Dec 04, The Universal Serial Bus 2. Views Read View source View history. I had at least two problems: Once I had to allow for the possibility of a more diverse HUB-based configuration, it just seemed simpler to treat the “root port” as a “root hub.
Is is controlled via memory mapped registers and cannot handle control transfers as a standard hub can. We did videoconferencing but using already compressed video from H cams.
A better use for this is, if you know the register name you’re looking for, by using grep we can reduce the amount of output. The ID pin within the adapter cable must be grounded.
Ralink info Other usefull info: I’ll keep plugging away.
