Hello, I connected a pen drive to USB port and I expected it to be recognized from Ubuntu. In fact it seems it does not power up, and no message can be found in dmesg output. lsusb output is this and nothing more: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub lsmod | grep -i usb shows these: usb_f_acm 5204 1 u_serial 9688 3 usb_f_acm usb_f_rndis 15931 1 usb_f_mass_storage 44068 2 g_multi u_ether 12278 2 usb_f_rndis,g_multi libcomposite 35715 4 usb_f_acm,usb_f_rndis,g_multi,usb_f_mass_storage usbmisc_imx 8816 1 ci_hdrc_imx usbcore 173703 2 ehci_hcd,ci_hdrc usb_common 3308 4 udc_core,libcomposite,usbcore,ci_hdrc Am I missing something? Can I use the USB port this way to connect a pen drive, or do I have to connect it through a powered USB hub? Or simply I found a broken USB port? Thanks, Stefano
When I put an USB pen drive in the large USB port it is automatically detected by Udoobuntu 2. I use a powered USB hub. When I put the pen drive in the hub before powering the Neo nothing will be detected, also not the mouse and keyboard. When I put it in the USB port directly (without powered hub) it is also detected.
Ok, so it seems that I have a problem... Tomorrow I will check with an USB tester if port gives correct supply to the pen drive; if so, it might be an hardware issue related to my board. A second chanche would be to install a fresh copy of UDOObuntu2, just to check if any upgrade to the system had caused some software issues. Thanks for your support. I'll keep you updated tomorrow.
Ok, this morning I tried with an USB tester. Device seems to be correctly powered. Now I'm creating a fresh SD card with UDOObuntu2, to check if a fresh copy of the system will let USB working. Cheers!
YEP! It works! On the fresh copy of UDOObuntu2 my pen drive is correctly recognized. So it should have been some upgrade to the previous installation which broke up something. I'll try to isolate what was the problem anyway. Thanks for your support.
