Hello, I do have problems with all my usb devices on my omap3-based boad (Beagle Board). For example I cannot move a file from a sub stick to the local filesystem. uname -a: Linux beagleboard 2.6.28-omap1 #2 Thu Jan 8 13:19:46 CET 2009 armv7l unknown strace output: ######################### strace mv /media/sda1/log.txt /home/root/ execve("/bin/mv", ["mv", "/media/sda1/log.txt", "/home/root/"], [/* 10 vars */]) = 0 brk(0) = 0x9f000 uname({sys="Linux", node="beagleboard", ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4001c000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/var/run/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=5760, ...}) = 0 mmap2(NULL, 5760, PROT_READ, MAP_PRIVATE, 3, 0) = 0x4001d000 close(3) = 0 open("/lib/libm.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\3101\0\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=431928, ...}) = 0 mmap2(NULL, 463008, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x40025000 mprotect(0x4008e000, 28672, PROT_NONE) = 0 mmap2(0x40095000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED| MAP_DENYWRITE, 3, 0x68) = 0x4009 5000 close(3) = 0 open("/lib/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\334K\1\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1111556, ...}) = 0 mmap2(NULL, 1147328, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x40097000 mprotect(0x401a3000, 28672, PROT_NONE) = 0 mmap2(0x401aa000, 12288, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED| MAP_DENYWRITE, 3, 0x10b) = 0x40 1aa000 mmap2(0x401ad000, 8640, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED| MAP_ANONYMOUS, -1, 0) = 0x401ad0 00 close(3) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4001f000 syscall_983045(0x4001f4a0, 0x4001f4a0, 0x684, 0x4001fb78, 0x40024058, 0x40024000, 0, 0xf0005, 0x58, 0x1, 0xffff5cc0, 0xbe9bcb44, 0, 0xbe9bc7e0, 0x400113b4, 0x40002018, 0x20000010, 0x4001f4a0, 0xc498, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0) = 0 mprotect(0x401aa000, 8192, PROT_READ) = 0 mprotect(0x40095000, 4096, PROT_READ) = 0 mprotect(0x40023000, 4096, PROT_READ) = 0 munmap(0x4001d000, 5760) = 0 getpid() = 1742 getuid32() = 0 stat64("/home/root/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 brk(0) = 0x9f000 brk(0xc0000) = 0xc0000 stat64("/home/root/log.txt", 0xbe9bcc38) = -1 ENOENT (No such file or directory) rename("/media/sda1/log.txt", "/home/root/log.txt") = -1 EXDEV (Invalid cross-device link) stat64("/media/sda1/log.txt", {st_mode=S_IFREG|0755, st_size=7388, ...}) = 0 lstat64("/media/sda1/log.txt", {st_mode=S_IFREG|0755, st_size=7388, ...}) = 0 lstat64("/home/root/log.txt", 0xbe9bcac8) = -1 ENOENT (No such file or directory) open("/media/sda1/log.txt", O_RDONLY|O_LARGEFILE) = 3 open("/home/root/log.txt", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0100755) = 4 read(3, "================================"..., 4096) = 4096 write(4, "================================"..., 4096) = 4096 read(3, "idth [ms]\"\n[40]: 0x3001, GRAB_RE"..., 4096) = 3292 write(4, "idth [ms]\"\n[40]: 0x3001, GRAB_RE"..., 3292) = 3292 read(3, "", 4096) = 0 close(4) = 0 close(3) = 0 fstatfs64(651376, 3197881000, {???}) = 0 chown32("/home/root/log.txt", 0, 0) = 0 chmod("/home/root/log.txt", 0100755) = 0 lstat64("/media/sda1/log.txt", {st_mode=S_IFREG|0755, st_size=7388, ...}) = 0 unlink("/media/sda1/log.txt"usb 1-1.4: <----Here it hangs for a minute----> reset high speed USB device using musb_hdrc and address 4 hub 1-1:1.0: cannot reset port 4 (err = -71) usb 1-1.4: device descriptor read/64, error -110 hub 1-1:1.0: cannot reset port 4 (err = -71) usb 1-1.4: device descriptor read/64, error -110 usb 1-1.4: reset high speed USB device using musb_hdrc and address 4 usb 1-1.4: device descriptor read/64, error -110 hub 1-1:1.0: cannot reset port 4 (err = -71) usb 1-1.4: device descriptor read/64, error -110 usb 1-1.4: reset high speed USB device using musb_hdrc and address 4 usb 1-1.4: device not accepting address 4, error -110 usb 1-1.4: reset high speed USB device using musb_hdrc and address 4 usb 1-1.4: device not accepting address 4, error -110 usb 1-1.4: USB disconnect, address 4 sd 0:0:0:0: Device offlined -
