Hi,
after recompiling kernel finally i can connect my solar inverter to raspi.

BUT... after first interrogation that works, second time i try to connect it gives me this error

any suggestion?

Hi,

If i get it correct, Raspberry use the same kernel as Oxnas boards (2.6.31.6) as it is an ARMv6 device. This version have many troubles with usbserial.
I know several users who run aurora with 123solar but they use raspbian.

The rpi has it's own (3.x) kernel

@tassheloff when you say "second time i try to connect " is this plugging in physically or run software?

[tassheloff]

@pepedog second time i run software.... sad sad thing.....

Can you give details of hardware, ie is it a powered hub, is rpi powered by that hub or separate power.
I found with separate power that voltage went back down to rpi from hub, so I power via hub now

[tassheloff]

i've read is a problem of debian core....

I' tried:
USB->SERIAL
CH341;
PL2303;
TI_3410

powered Hub
direct connection
active amplified usb cord

Pogoplug pro
raspberry pi

All same problem... second read in a row will hang solar aurora power-one 6000outd inverter

Has anyone solved the problem for connecting the TI_USB to Raspi, please?
If not can anyone suggest what actions I could take to solve the problem.
