Raspberry pi as a server, Windows 10 as client

Hello, I installed a server on pi3, then plug my device to usb. Unfortunately windows is not seeing this device. Is there any way to debug this? My device is FLEX-1500 that i want to share.
Output of dmesg in rpi:
usb 1-1.1.2: device not accepting address 7, error -32
usb 1-1.1-port2: unable to enumerate USB device
usb 1-1.1.1: new high-speed USB device number 8 using dwc_otg
usb 1-1.1.1: New USB device found, idVendor=0424, idProduct=7800, bcdDevice= 3.00
usb 1-1.1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0

Second fix worked!
Many thanks! Now I will start testing :D
