[d9394]

docker-rsptcpserver run out error:
rsp_tcp version 1.0
libmirsdrapi-rsp version 2.13 found
fwDownload: FW image size = 6008
libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/002/002: No such device
Error: libusb_open() -1
no RSP devices available.

Here is synlogy info use lsusb:
_usb2 1d6b:0002:0310 09 2.00 480MBit/s 0mA 1IF (Linux 3.10.105 etxhci_hcd-170202 Etron xHCI Host Controller 0000:04:00.0) hub
|__2-1 1df7:2500:0206 ff 2.00 480MBit/s 400mA 1IF ( 0000000001)

usb2-1 1df7:2500 is connecting to rsp1 device

[d9394]

after I use command: ln -s /dev/bus/usb/002/001 /dev/bus/usb/002/002
then rsp_tcp can found the rsp1 device and run properly.
