Hello, I changed usb.c and crossompiled it for samsung nexus s(exynos SoC). arm-linux-gnueabi-gcc -static usb.c usbstring.c -lpthread
In the kernel I enable gadgetfs module with s3c-udc(s3c_udc_otg.c) I can mount gadgetfs, but when I run the binary with verbose flag I get following output on device side: /dev/gadget/s3c-udc ep0 configured serial="adfczl3sdf39idgfo7tdsfv2ss6l3tarbfdfsdjs5m2uffusdflwmfgfs" ** Thu Jan 1 00:38:19 1970 CONNECT high speed DISCONNECT CONNECT high speed DISCONNECT CONNECT high speed DISCONNECT CONNECT high speed DISCONNECT CONNECT high speed DISCONNECT CONNECT high speed and on the Host: [ 5453.889566] usb 2-1.5: device descriptor read/64, error 18 [ 5454.065627] usb 2-1.5: device descriptor read/64, error 18 [ 5454.241502] usb 2-1.5: new high-speed USB device number 4 using ehci-pci [ 5454.313667] usb 2-1.5: device descriptor read/64, error 18 [ 5454.489593] usb 2-1.5: device descriptor read/64, error 18 [ 5454.665655] usb 2-1.5: new high-speed USB device number 5 using ehci-pci [ 5454.686276] usb 2-1.5: device descriptor read/8, error -61 [ 5454.806488] usb 2-1.5: device descriptor read/8, error -61 [ 5454.981641] usb 2-1.5: new high-speed USB device number 6 using ehci-pci [ 5455.014346] usb 2-1.5: device descriptor read/8, error -71 [ 5455.146450] usb 2-1.5: device descriptor read/8, error -71 If I sniff the communication with Wireshark, there is an error message: malformed package Please help!
