i still can't figure out is it a hardware or configuration problem, i can see all registers, drivers seems to work, it can detect device insert but there is no data transmision
there are also no interrupts, i'm not sure what to write in interrupt_line in PCI config space any hints? ============================================================= here is my dmesg part: ehci_hcd 00:1e.2: PCI device 1033:00e0 ehci_hcd 00:1e.2: irq -20, pci mem c924b000 usb.c: new USB bus registered, assigned bus number 1 ehci_hcd 00:1e.2: ehci_start hcs_params 0x2385 dbg=0 cc=2 pcc=3 !ppc ports=5 ehci_hcd 00:1e.2: ehci_start portroute 1 0 1 0 0 ehci_hcd 00:1e.2: ehci_start hcc_params e806 thresh 0 uframes 256/512/1024 park ehci_hcd 00:1e.2: capability 0001 at e8 ehci_hcd 00:1e.2: reset command 080b02 park=3 ithresh=8 period=1024 Reset HALT PCI: 00:1e.2 PCI cache line size set incorrectly (0 bytes) by BIOS/FW, correcting to 32 ehci_hcd 00:1e.2: init command 010b09 park=3 ithresh=1 period=256 RUN ehci_hcd 00:1e.2: USB 2.0 enabled, EHCI 1.00, driver 2003-Dec-29/2.4 hcd.c: 00:1e.2 root hub device address 1 usb.c: kmalloc IF c727f340, numif 1 usb.c: new device strings: Mfr=3, Product=2, SerialNumber=1 usb.c: USB device number 1 default language ID 0x0 Manufacturer: Linux 2.4.19-dgt ehci_hcd Product: PCI device 1033:00e0 SerialNumber: 00:1e.2 hub.c: USB hub found hub.c: 5 ports detected hub.c: standalone hub hub.c: ganged power switching hub.c: individual port over-current protection hub.c: Single TT hub.c: TT requires at most 8 FS bit times hub.c: Port indicators are not supported hub.c: power on to power good time: 0ms hub.c: hub controller current requirement: 0mA hub.c: port removable status: RRRRR hub.c: local power source is good hub.c: no over-current condition exists hub.c: enabling power on all ports usb.c: hub driver claimed interface c727f340 ehci_hcd 00:1e.2: GetStatus port 1 status 001803 POWER sig=j CSC CONNECT hub.c: port 1, portstatus 501, change 1, 480 Mb/s hub.c: port 1 connection change hub.c: port 1, portstatus 501, change 1, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms ehci_hcd 00:1e.2: port 1 full speed --> companion ehci_hcd 00:1e.2: GetStatus port 1 status 003801 POWER OWNER sig=j CONNECT hub.c: port 1, portstatus 0, change 10, 12 Mb/s ehci_hcd 00:1e.2: free_config devnum 0 hub.c: port 2, portstatus 100, change 0, 12 Mb/s hub.c: port 3, portstatus 100, change 0, 12 Mb/s hub.c: port 4, portstatus 100, change 0, 12 Mb/s hub.c: port 5, portstatus 100, change 0, 12 Mb/s
