Héllo All,

I made some few tests on EspressoBin-Ultra from GlobalScaleTechnologies,
because of problem with the WiFi.

I have done some quick tests on all the firmware of PCIEUSB-8997 using
the pcieuart8997_combo_v4.bin on OpenWrt 21.02.x

Here is a summary of the tests :
- W16.68.10.p159 = KO
- W16.68.1.p195 = KO
- V16.68.1.p145 = OK
- 16.68.1.p140 = OK
- 16.68.1.p133 = OK
- 16.68.1.p97 = OK
- 16.68.1.p70 = KO

Olders looks to works better.

In quick tests, they allow more than 1 clients at a time !

I am still testing the V16.68.1.p145 and report the results after some
longer use...

Hopes it will help...
