I opened bug #991004 to have the compat package in Ubuntu. Then installed it manually as described there. Now I have:
$ ldd /usr/sbin/usb_modeswitch linux-gate.so.1 => (0xb7769000) libusb-0.1.so.4 => /usr/local/lib/libusb-0.1.so.4 (0xb7742000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb759d000) libusb-1.0.so.0 => /lib/i386-linux-gnu/libusb-1.0.so.0 (0xb758c000) /lib/ld-linux.so.2 (0xb776a000) librt.so.1 => /lib/i386-linux-gnu/librt.so.1 (0xb7583000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb7568000) so the compat version in /usr/local/lib is used, but it still fails: USB description data (for identification) ------------------------- Manufacturer: ZTE,Incorporated Product: ZTE LTE Technologies MSM Serial No.: MF820DFFFS111111 ------------------------- Looking for active driver ...
