Rerty.... news on usbserial or usbcore?

[tassheloff]

Hi all... i try reposting my problem hoping that someone has the solution.

When I plug a usb to rs485 adapter (but also a usb to RS232) and i try to communicate I found first communication ok , second communication hangs up all USB system, e.g. if I try to connect a USB disk after first communication it dont's come up.

For millions of try i've done i'm sure problem is in archlinuxarm usb manage module....

There is some hope in quick updates to these modules? There are workarounds?

Thanks in advance and Happy Easter to all

The workaround already exists, but you'll have to take the responsibility of applying it yourself ...

Hi Telzey,

is there any way (at the moment) to get the 2.6.31.14 kernel work on a USB drive (instead of SATA drive)?

Thank you

I'm waiting the serial cable

To use the 2.6.31.14 kernel for a USB install of ALARM you'll have to write the kernel to NAND memory and replace the default ALARM 2.6.31.6 kernel that was written during your initial installation of ALARM.

This isn't particularly difficult, but it must be done EXACTLY right. If you don't flash it to NAND correctly, or if your kernel doesn't work (because you didn't test it), then you can only recover if you either have a serial cable, or if you boot directly from SATA.

It should work fine, but I'm not in the position to help out tens or hundreds of angry users that failed to follow the correct steps. That's why I'm not recommending it, and not giving out instructions on how to do it.

If you have a working serial cable, then you can always build and test the kernel first by using a tftp boot. I believe that's what WarheadsSE does when testing his kernels. I just write mine to a SATA drive (but also with a serial cable to see the boot messages).

Either way you're going to have to open up your Pogoplug and spend a little money on cables.

Ok, now it is very clear!

Thank you! I think I'm going to wait
I'm just entering in Linux world and I have to say that it is interesting, but it is not so plain and I don't want to make my pogoplug a unuseful paperweight.
