How to connect from Linux to BleemSync 1.1

After installing BleemSync 1.1 on my PlayStation Classic, I could connect to the BleemSync UI from Windows but not from Linux (Ubuntu 19.04). Google Chrome reported "unable to connect," and ping to reported a network error.

dmesg showed that Linux identified the device, and RNDIS networking started

[23945.137399] usb 1-3: new high-speed USB device number 31 using xhci_hcd

However, ifconfig showed it did not have an IPv4 address. This indicates a DHCP failure.

$ ifconfig enp0s20f0u3
enp0s20f0u3: flags=4163  mtu 1500
        inet6 fe80::adf4:a447:4b1d:f96c  prefixlen 64  scopeid 0x20
        ether 72:b7:b8:ae:c8:00  txqueuelen 1000  (Ethernet)
        RX packets 8  bytes 536 (536.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 81  bytes 12347 (12.3 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

I bypassed DHCP by manual IP configuration.

sudo route add -net netmask metric 1024 dev enp0s20f0u3
sudo ifconfig enp0s20f0u3

Now Google Chrome, ping, and even telnet worked.

Note: your interface name may vary. Mine was enp0s20f0u3.

This solution worked until rebooting Ubuntu. Later I found a permanent solution: BleemSync 1.0 on Ubuntu thanks to DDFoster96.
