We are making progress. If you can get USB hub 1. You may need the extra voltage. The code was running, but it was ridiculously slow. I wonder how an usb client knows if the host is a high speed or full speed device. Thanks Duck, A lot of great information Looks like I’ll be working on this for a little while.

Many confuse other issues in with the core problem. The driver is built in Ubuntu 8.

You should just be able to double click on the file, and File Roller should open and it is pretty self evident from there. My experience with a few different branded serial to usb adapters has been good perhaps yours is good too. It still locks up with a clean install onto a new SD card.

Product Drivers & Firmware

I tried to upgrade but still it was not improving. This would also point into the direction that some interrupts aren’t handeled upon their first occurence. I need to figure out how to crosscompile on my other machine to get a kernel full of more debug info and possibly a way to break the hardlock without rebooting. I am unsure if this is described in the broadcom soc datasheet.



Select all Sep 1 The system is running at MHz. ECC disabled, Data cache writeback [ 0. Like the usb2serial dongles It’s not a solution, but it could be a workaround untill a better solution is found. However it may settle down when I’m through experimenting.

The search link is on the raspberrypi. If so, how can I do it? He seems to have access to even the synoptic hardware verilog description files. The driver which came with the adapter is for a Windows application. My guess is that the automatic update is not working correctly, it was a bit annoying to re-install everything again in the SD card, but it was worthy. I edited cmdline on the SD card in another computer and managed to log in again.

I think I paid I booted with only the keyboard 50mA connected, then removed it and plugged in the alarm connection, so there shouldn’t be any load on the USB.

How guc232s I un-zip it to access it?

It will barely light an LED. I know that’s not much to work with. Seems like they never expected it to happen, so they didn’t bother to write code in gguc232a driver for it.


New USB device strings: You may see me on again later. It also seems that connecting and using an guc232w adapter to the Pi makes the number of interrupts dramatically increase again. I guc223a, do you dev’s have an irc channel you use to exchange thoughts? Why do you think it is locked up permanently in that function?

Failed to read register index 0x Sep 1 Don’t use an input steering diode.

Do you have any evidence that it isn’t leaving tuc232a function. Maybe it’s possible to force specific devices to fullspeed. I wonder how an usb client knows if the host is a high speed or full speed device. Last edited by M33P on Sat Mar 09, 6:
