  • Forum Post: USB Host controller

    manuel
    Hi, Did anyone got the USB interface of the OMAP3503 EVM working with Linux ? I want to connect a USB sound card, and it just does nothing. I do not get a USB event when I plug in any USB device. Just nothing happens. The USB Host driver is built in, detects one HUB Root, but thats it. As far as I understand...

    This is indeed the better place for this type of question :) The OMAP35x SDK does provide support for USB devices, and it has been tested, though there are several limitations still present with the USB drivers as discussed in section 2.6 of the PSP release notes . You do have to have a MiniA ended...

    Hi, thanks for the reply. I already had considered all the details posted so far. I also checked the cable if the ID pin was actually connected to ground, and it was as it should be. So the cable is not broken or something like that. Im also using a powered HUB. When I do a "cat /proc/driver/musb_hdrc...

    Hi everyone, It turned out that my OMAP35x board was broken. I tried another different board one, and USB devices are detected just fine. But, it does not work either. Either with the original SDK 1.0.0 default kernel or custom kernel with different USB driver settings (experimental code for better transaction...

    Hi, thanks for replying, but I have been using ALSA for several years (as user, driver and application developer), and I have never had any problems with multichannel. I also have other ARM based systems working just fine with the very same audio cards in multichannel mode. I will try using another USB...

    Good to know that you are familiar with the ALSA infrastructure quite a bit. We had an issue with the usbaudio.c code in "sound/usb" directory were the USB flags were not correctly updated. This lead to random oops after recording stopped. We corrected the issue by correctly updating the...

    Hi, Thanks for the information. I did some googling about that. Does this problem show up under any circumstance or only if I request explicitly the ASYNC mehtod ? The error message that is supposed to reveal this problem seems to be "file descriptor in wrong state" or something like that....

    Sorry, I was focusing too much on the audio portion of the issue and blocked out the USB. Based on the log you sent earlier, it appears the USB device is not being recognized; therefore this is not an ALSA/audio issue but rather a USB device interface issue. I agree ALSA supports multiple channels...

    I am glad to hear you could get to the schematics, hopefully they are helpful. As to your USB issues, though I have not used the Gumstix board I did go through a bit of trouble to get the Beagle Board USB working, I made a post a couple days ago at https://community.ti.com/forums/p/1889/6931.aspx#6931...

    DV Could someone give me the run down on the differences between the USB host PHY mode vs. TTL mode? The TLL mode, or Transceiverless Link Logic, is meant to support a connection from say the OMAP35xx and another processor, or modem, that supports the TLL mode. This allows connecting 2 USB interfaces...

    It seems to work right now, but there is another problem. Addres is set on the device but USB IC seems to don't accept any new requests on new address, the Host will then reset the device and story goes 3 times all over again.
