Hello All,
I am trying to use EHS5 EVM on fedora 17 but the enumeration fails every time i try to connect it.
It would be very helpful if this issue is resolved.
Thanks and Regards

Hello,
Fedora 17 is quite an old version. Most probably it's too old. You need a newer version with newer kernel for this to work or you would need to integrate the drivers on your own.

If i can get some workaround which can enable EHS5x connect to GPRS network it would be very helpful.
Hello,
There are no propriety drivers needed - you need a standard cdc_acm driver. If it's not integrated into your kernel you'd need to add it. So you should check linux forums for more information.

Hello,
I have updated the driver in kernel device is getting enumerated but connetion to ISP is not possible. So if there are changes suggested in ppp chat script it would be very convinent.

Hello,
I have updated the driver in kernel, device is getting enumerated now but unable to connect to the ISP. AT+CME error 100 can be seen on wireshark. Are there some known changes on pppd side which we can implement and test.

Do you know what exactly fails? Do you have any log? It would be easier to help then.

Hello Bartłomiej,
I have attached dmesg and logs from /var/logs/messages file and I have seen some logs on wireshark which informs that after AT+CME error 100 response no command is being sent form host.

Hello,
Could you please paste the log with all AT commands and replies? That should shed some more light on the problem.
Thanks,
Bartłomiej
Hello Bartłomiej,
Since we are using USB to connect to Ehs5x i can only provide wireshark logs as all the AT commands are sent through USB. Is it fine by you.
Thanks and Regards

you can find the file on this link.
You can put filter usb.device_address == 6
I think error comes when at+ws46=? command is sent
