AFAIK there's actually no way to disable the role switching in MUSB hardware, the hardware tries to do things on it's own anyways. So it's probably best to always set it to CONFIG_USB_MUSB_DUAL_ROLE=y unless size of the code is an issue. > > I noticed that this only works with CONFIG_USB_MUSB_HDRC and > > CONFIG_TWL4030_USB built into the kernel.

I found the core issue with loadable modules, we currently need to have just one platform glue layer module compiled in. I have a fix coming up for that.. > It's weird, for me fails in both cases, built-in and with loadable > modules.

Maybe check your MUSB configuration one more time. See the attached patch, but note you need to only select the glue layer for the CONFIG_USB_MUSB_OMAP2PLUS option and disable other glue layer module options. Also, you may want to monitor the VBUS line in host mode. If the VBUS does not come up fast enough, MUSB hardware will give up as it's again trying to do things on its own. > > And on the 37xx EVM, I've never had any luck getting any twl4030_usb > > interrupts for some reason. Turns out the 37xx EVM is using an isp1507 phy instead of the twl4030 phy. The proper fix for that will be to start using the usb-nop-xceiv or phy-ulpi when we have drivers/phy/ driver for it. Right now trying to use it seems to fail with the following error: HS USB OTG: no PHY configured Regards, Tony 8< ------------- From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Mon, 17 Nov 2014 07:53:59 -0800 Subject: [PATCH] ARM: omap2plus_defconfig: Enable USB as loadable modules NOTE: Currently only one MUSB glue layer can be selected below because of the ifdefs, I'll do a fix for that. --- a/arch/arm/configs/omap2plus_defconfig +++ b/arch/arm/configs/omap2plus_defconfig @@ -270,17 +270,92 @@ CONFIG_SND_OMAP_SOC_OMAP_ABE_TWL6040=m CONFIG_SND_OMAP_SOC_OMAP3_PANDORA=m CONFIG_USB=y CONFIG_USB_ANNOUNCE_NEW_DEVICES=y +CONFIG_USB_DYNAMIC_MINORS=y +CONFIG_USB_OTG=y CONFIG_USB_MON=y CONFIG_USB_WDM=y CONFIG_USB_STORAGE=y +CONFIG_USB_MUSB_HDRC=m +CONFIG_USB_MUSB_TUSB6010=m +CONFIG_USB_MUSB_OMAP2PLUS=m +CONFIG_USB_MUSB_AM35X=m +CONFIG_USB_MUSB_DSPS=m CONFIG_USB_DWC3=m -CONFIG_USB_TEST=y -CONFIG_AM335X_PHY_USB=y +CONFIG_USB_SERIAL=m +CONFIG_USB_SERIAL_GENERIC=y +CONFIG_USB_SERIAL_SIMPLE=m +CONFIG_USB_SERIAL_FTDI_SIO=m +CONFIG_USB_SERIAL_PL2303=m +CONFIG_USB_EMI62=m +CONFIG_USB_EMI26=m +CONFIG_USB_ADUTUX=m +CONFIG_USB_SEVSEG=m +CONFIG_USB_RIO500=m +CONFIG_USB_LEGOTOWER=m +CONFIG_USB_LCD=m +CONFIG_USB_LED=m +CONFIG_USB_CYPRESS_CY7C63=m +CONFIG_USB_CYTHERM=m +CONFIG_USB_IDMOUSE=m +CONFIG_USB_FTDI_ELAN=m +CONFIG_USB_APPLEDISPLAY=m +CONFIG_USB_SISUSBVGA=m +CONFIG_USB_SISUSBVGA_CON=y +CONFIG_USB_LD=m +CONFIG_USB_TRANCEVIBRATOR=m +CONFIG_USB_IOWARRIOR=m +CONFIG_USB_TEST=m +CONFIG_USB_EHSET_TEST_FIXTURE=m +CONFIG_USB_ISIGHTFW=m +CONFIG_USB_YUREX=m +CONFIG_USB_EZUSB_FX2=m +CONFIG_USB_HSIC_USB3503=m +CONFIG_USB_LINK_LAYER_TEST=m +CONFIG_NOP_USB_XCEIV=y +CONFIG_AM335X_PHY_USB=m +CONFIG_TWL6030_USB=m +CONFIG_USB_GPIO_VBUS=m +CONFIG_USB_ISP1301=m +CONFIG_USB_ULPI=y CONFIG_USB_GADGET=y CONFIG_USB_GADGET_DEBUG=y CONFIG_USB_GADGET_DEBUG_FILES=y CONFIG_USB_GADGET_DEBUG_FS=y +CONFIG_USB_CONFIGFS=m +CONFIG_USB_CONFIGFS_SERIAL=y +CONFIG_USB_CONFIGFS_ACM=y +CONFIG_USB_CONFIGFS_OBEX=y +CONFIG_USB_CONFIGFS_NCM=y +CONFIG_USB_CONFIGFS_ECM=y +CONFIG_USB_CONFIGFS_ECM_SUBSET=y +CONFIG_USB_CONFIGFS_RNDIS=y +CONFIG_USB_CONFIGFS_EEM=y +CONFIG_USB_CONFIGFS_MASS_STORAGE=y +CONFIG_USB_CONFIGFS_F_LB_SS=y +CONFIG_USB_CONFIGFS_F_FS=y CONFIG_USB_ZERO=m +CONFIG_USB_ZERO_HNPTEST=y +CONFIG_USB_AUDIO=m +CONFIG_GADGET_UAC1=y +CONFIG_USB_ETH=m +CONFIG_USB_ETH_EEM=y +CONFIG_USB_G_NCM=m +CONFIG_USB_GADGETFS=m +CONFIG_USB_FUNCTIONFS=m +CONFIG_USB_FUNCTIONFS_ETH=y +CONFIG_USB_FUNCTIONFS_RNDIS=y +CONFIG_USB_FUNCTIONFS_GENERIC=y +CONFIG_USB_MASS_STORAGE=m +CONFIG_USB_G_SERIAL=m +CONFIG_USB_MIDI_GADGET=m +CONFIG_USB_G_PRINTER=m +CONFIG_USB_CDC_COMPOSITE=m +CONFIG_USB_G_ACM_MS=m +CONFIG_USB_G_MULTI=m +CONFIG_USB_G_MULTI_CDC=y +CONFIG_USB_G_HID=m +CONFIG_USB_G_DBGP=m +CONFIG_USB_LED_TRIG=y CONFIG_MMC=y CONFIG_SDIO_UART=y CONFIG_MMC_OMAP=y @@ -310,6 +385,7 @@ CONFIG_PWM_TWL=y CONFIG_PWM_TWL_LED=y CONFIG_OMAP_USB2=y CONFIG_TI_PIPE3=y +CONFIG_TWL4030_USB=m CONFIG_EXT2_FS=y CONFIG_EXT3_FS=y # CONFIG_EXT3_FS_XATTR is not set -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
