Thanks, I CCed both linux-usb and linux-omap.
CONFIG_OMAP_OCP2SCP should also be enabled. omap usb2 phy is connected to ocp2scp. Only during ocp2scp probing omap usb2 phy will be created. In your case ocp2scp is not enabled and hence omap usb2 phy is not created. Btw which defconfig did you use? we have enabled it in omap2plus_defconfig ;-)
Hello, thanks for the hint. Going to try this out this evening. Concerning the defconfig, I based my current config on the defconfig from 3.12-rc4, at that time CONFIG_OMAP_OCP2SCP wasn't enabled yet (looks like you only just recently added it).
So I added CONFIG_OMAP_OCP2SCP and this at least let's me progress partially. This is what I get: musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) musb-hdrc: MHDRC RTL version 2.0 musb-hdrc: setup fifo_mode 4 musb-hdrc: 28/31 max ep, 16384/16384 memory musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 3 usb usb3: New USB device found, idVendor=1d6b, idProduct=0002 usb usb3: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb usb3: Product: MUSB HDRC host driver usb usb3: Manufacturer: Linux 3.12.0+ musb-hcd usb usb3: SerialNumber: musb-hdrc.1.auto hub 3-0:1.0: USB hub found hub 3-0:1.0: 1 port detected twl6030_usb usb-comparator.26: Initialized TWL6030 USB module musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active musb_bus_suspend 2457: trying to suspend as a_idle while active The last message is repeated ad infinitum and quickly fills my root partition. I tried this both with the OTG cable connected and not (also with cable connected before boot). The device attached to the port also isn't powered when I insert the relevant modules (the optical output of the usb-audio stick then lights up). I currently have the driver compiled in 'host mode only' mode. The musb_bus_suspend seems to come from musb_host. I'm now recompiling with 'dual role' mode, maybe this gets me further.
Now tested with 'dual role', which at least fixes the kernel log spamming. Device still doesn't work though. Again I tried everything with either OTG cable plugged in from before boot, plugging in after module load, not plugged in at all. Also, this happens when I try to switch musb into host mode: echo -n host > /sys/devices/44000000.ocp/4a0ab000.usb_otg_hs/musb-hdrc.1.auto/mode dmesg: [ 273.218292] musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) [ 273.218353] musb-hdrc: MHDRC RTL version 2.0 [ 273.218353] musb-hdrc: setup fifo_mode 4 [ 273.218383] musb-hdrc: 28/31 max ep, 16384/16384 memory [ 273.218444] musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver [ 273.218444] musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 3 [ 273.218749] usb usb3: New USB device found, idVendor=1d6b, idProduct=0002 [ 273.218780] usb usb3: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 273.218780] usb usb3: Product: MUSB HDRC host driver [ 273.218811] usb usb3: Manufacturer: Linux 3.12.0+ musb-hcd [ 273.218811] usb usb3: SerialNumber: musb-hdrc.1.auto [ 273.219451] hub 3-0:1.0: USB hub found [ 273.219482] hub 3-0:1.0: 1 port detected [ 273.243804] twl6030_usb usb-comparator.26: Initialized TWL6030 USB module [ 327.561157] ------------[ cut here ]------------ [ 327.561492] WARNING: CPU: 0 PID: 0 at drivers/bus/omap_l3_noc.c:113 l3_interrupt_handler+0xc0/0x164() [ 327.561492] L3 custom error: MASTER:MPU TARGET:L4CFG [ 327.561492] Modules linked in: phy_twl6030_usb omap2430 musb_hdrc btrfs xor xor_neon zlib_inflate zlib_deflate raid6_pq omapfb cfbfillrect cfbimgblt cfbcopyarea arc4 wl12xx wlcore mac80211 cfg80211 rfkill usb_storage wlcore_sdio [ 327.561553] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.12.0+ #3 [ 327.561553] Backtrace: [ 327.561553] [<c0011988>] (dump_backtrace+0x0/0x10c) from [<c0011b24>] (show_stack+0x18/0x1c) [ 327.561676] r6:00000071 r5:00000009 r4:00000000 r3:00000000 [ 327.561676] [<c0011b0c>] (show_stack+0x0/0x1c) from [<c03f4f90>] (dump_stack+0x78/0x94) [ 327.561676] [<c03f4f18>] (dump_stack+0x0/0x94) from [<c0032cf0>] (warn_slowpath_common+0x6c/0x90) [ 327.561676] r4:c054fe28 r3:c054c3f4 [ 327.561676] [<c0032c84>] (warn_slowpath_common+0x0/0x90) from [<c0032db8>] (warn_slowpath_fmt+0x38/0x40) [ 327.561676] r8:0000002a r7:c04d0898 r6:c05735d0 r5:f8000400 r4:00080003 [ 327.561798] [<c0032d80>] (warn_slowpath_fmt+0x0/0x40) from [<c01e7560>] (l3_interrupt_handler+0xc0/0x164) [ 327.561798] r3:c05735d4 r2:c04d085c [ 327.561798] [<c01e74a0>] (l3_interrupt_handler+0x0/0x164) from [<c006d508>] (handle_irq_event_percpu+0x54/0x19c) [ 327.561798] r7:00000000 r6:00000000 r5:ed007054 r4:ed0ca2c0 [ 327.561798] [<c006d4b4>] (handle_irq_event_percpu+0x0/0x19c) from [<c006d69c>] (handle_irq_event+0x4c/0x6c) [ 327.561889] [<c006d650>] (handle_irq_event+0x0/0x6c) from [<c0070708>] (handle_fasteoi_irq+0x84/0x150) [ 327.561889] r6:00000000 r5:0000002a r4:ed007000 r3:00000000 [ 327.561920] [<c0070684>] (handle_fasteoi_irq+0x0/0x150) from [<c006ce98>] (generic_handle_irq+0x28/0x38) [ 327.561920] r4:0000002a r3:c0070684 [ 327.561950] [<c006ce70>] (generic_handle_irq+0x0/0x38) from [<c000f0b8>] (handle_IRQ+0x40/0x9c) [ 327.561950] r4:c054cc7c r3:000001a8 [ 327.561981] [<c000f078>] (handle_IRQ+0x0/0x9c) from [<c00084d4>] (gic_handle_irq+0x30/0x64) [ 327.561981] r6:c054ff38 r5:c05567f4 r4:fa24010c r3:000000a0 [ 327.562011] [<c00084a4>] (gic_handle_irq+0x0/0x64) from [<c0012600>] (__irq_svc+0x40/0x50) [ 327.562011] Exception stack(0xc054ff38 to 0xc054ff80) [ 327.562042] ff20: c0dd28d0 00000000 [ 327.562042] ff40: 00055b34 c0025644 c0585cac 00000001 c0585cac c0556468 c03fd14c c054e000 [ 327.562072] ff60: c0556408 c054ff8c c054ff80 c054ff80 c0025270 c000f454 a00f0113 ffffffff [ 327.562072] r7:c054ff6c r6:ffffffff r5:a00f0113 r4:c000f454 [ 327.562103] [<c000f430>] (arch_cpu_idle+0x0/0x38) from [<c006cbb0>] (cpu_startup_entry+0x68/0x138) [ 327.562133] [<c006cb48>] (cpu_startup_entry+0x0/0x138) from [<c03f1ea8>] (rest_init+0x68/0x80) [ 327.562133] r7:ffffffff r3:00000000 [ 327.562133] [<c03f1e40>] (rest_init+0x0/0x80) from [<c051fa30>] (start_kernel+0x278/0x2bc) [ 327.562133] [<c051f7b8>] (start_kernel+0x0/0x2bc) from [<80008070>] (0x80008070) [ 327.562194] ---[ end trace 5c8243954ffb31e2 ]---

Abandoning, since I don't own the device anymore.
