USB2 supports speeds up to 480 Mbps, but the HW solution of the USB interface TBS (Cypress) is limited to 111.6 Mbps

Yes, i have same issues with 5530/5930 released drivers, Win7 and AltDVB. TS stream corrupted after several switches btw multistream transponders. I make fixed 5930 driver - ISI selection fixed and look like no more TS corruption. https://sourceforge.net/projects/crazyscan/files/test/TBS5930-debug....

A similar problem with unstable stream in USB device occurred when changing the FEC from 5/6 (111Mbit) to 8/9 (119Mbit)

What is your signal level in the problematic device? For DVB-S2/16APSK 4/5 it should reach at least 11dB.
Another problem (quite significant) is the maximum bandwidth of the USB bus in the TBS5930.

A little historical portal about ABS-S reception in Central Europe

Thanks, to "historic" reply

A long time ago, TBS produced a card only for the reception of the ABS-S standard for ChinaSat satellites.
Does anyone know or remember the details about card ?

TBS5590 ?

Is it possible to test TBS5930 also on 19E-11023.50 H SR-23500 FEC-3/4 ?
