Router Kasda from bezeq has a looped web UI. USB port does not mentioned anywhere. However this router has telnet, stripped down ssh interfaces and linux shell. So it is easy to check that the router can mount USB drive but SMB sharing is completely absent. Search for new firmware for Kasda was with no result. Attempt to install openwrt for this chip also failed. Later I have noted that Kasda router has Italian analog named Digicom and Digicom router has firmware update. Using TFTP64 one can upload digicom firmware and transform Kasda to Digicom which includes working file sharing and print server excluded by Bezeq.
