Hi everyone, I have a USB problem. I have already posted it on USB mailing list where Fabio Estevam can reproduce it on mx27pdk and mx31pdk (see http://www.spinics.net/lists/linux-usb/msg84305.html). I thought that it is maybe a "newbie" question/error (because I am) so here I am :) My configuration is an IMX27 with an ISP1504 with a 3.8.2 kernel. I tested it with a SMSC USB3340 transceiver where the same error appears with ULPI (for a OTG and H2 port) : ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver ehci-mxc: Freescale On-Chip EHCI Host driver mxc-ehci mxc-ehci.2: initializing i.MX USB Controller timeout polling for ULPI device mxc-ehci mxc-ehci.2: unable to init transceiver, probably missing mxc-ehci mxc-ehci.0: initializing i.MX USB Controller timeout polling for ULPI device mxc-ehci mxc-ehci.0: unable to init transceiver, probably missing I have read the datasheet of the two USB transceiver. On the SMSC USB3340, we have some gpios on RESET_B and I put it in high in the init board code. With this, it should have been correctly initialiazed (right ?) but there is again this "timeout" of ULPI. Do you have already seen this "error" ? What is it due to ? A mistake in the init configuration ? Thank you in advance for any help to understand how ULPI is working and what I am certainly doing wrong. -- Mylène JOSSERAND Navocap
