Other Parts Discussed in Thread: PCM2906B, PCM2902C, PCM2902

I'm working with 4 CI PCM2906B connected to a TUSB2046, seeing the consumption of 2906 connect an external source, but also windows tells me that the hub has run out of energy, as I fix this .. ??

Thank you very much.

Matias.

    Hi Matias,

    Perhaps this is related to the Max Power descriptor of each PCM2906B.
    Have you tried with PCM2902C?
    PCM2906B descriptor states Max Power as 500mA and PCM2902C as 100mA.

    Best regards,

    Hi Ivan, with PCM2902 works perfectly, which is why you add an external power supply, I only are leaving these PCM2906 and wanted to use them if I feed the 4 PCM2906 with an external fiente 2 amperes should not work well .. ??

    Sorry for English, Spanish is translated by Google.

    Thanks for your prompt response.
