Unable to access the USB device

[susedv]

I'm unable to access the USB device connected to Android.
According to dmesg the USB device is attached as "1-1.4", but the app is unable to parse it.
And if binding to "1-1" a strange error occurs I don't understand.

Client: Windows 10 Pro x64 with usbip v0.3.5

First attempt

C:\usbip-win>usbip --debug attach -r 192.168.35.10 -b 1-1
usbip: debug: usbip.c:151:[run_command] running command: attach
usbip: debug: usbip_network.c:175:[usbip_net_recv_op_common] request failed: status: ST_NA
usbip: debug: usbip_attach.c:142:[query_import_device] failed to recv common header: ERR_STATUS
usbip: debug: usbip_attach.c:144:[query_import_device] op code error: ST_NA
usbip: error: failed to attach

Second attempt

C:\usbip-win>usbip --debug attach -r 192.168.35.10 -b 1-1.4
usbip: debug: usbip.c:151:[run_command] running command: attach
usbip: debug: usbip_network.c:151:[usbip_net_recv_op_common] usbip_net_recv failed: -1
usbip: debug: usbip_attach.c:142:[query_import_device] failed to recv common header: ERR_NETWORK
usbip: error: failed to attach

On Debian Linux 9 client it looks similarly (tested with 1-1 and 1-1.4):

sudo usbip --debug attach -r 192.168.35.10 -b 1-1
usbip: debug: usbip.c:141:[run_command] running command: `attach'
usbip: debug: usbip_network.c:183:[usbip_net_recv_op_common] usbip_net_recv failed: -1
usbip: error: recv op_common
usbip: error: query

Server: Android 9 (aarch64)
