File server not working with samba

[Gaetano Vocca]

Dear all,
this is my first post on this list. I would like to say hello to everybody and 
thank you in advance for your help.

Here comes the problem description.
I have a Siemens sx541 access point with the feature of file server. It means 
I can plug a usb storage and I can publish one of the directories of this 
storage by means of the access point itself. The sx541 appears in the network 
like a Windows machine sharing a folder. 
The bad is that this folder is not usable with Linux+Samba. I am able to mount 
the share without problems but I can browse it only using the "oldattr" 
options when mounting it. Even with "oldattr", when I try to access any of 
the files on the share I get a "No such file or directory" error.
I have captured and attached the ethereal traces both under Linux and under 
Windows.
The sequence is: mount the share, list the content on the root, try to copy a 
little file, unmount it.
Everything works with Win but not with Linux.

Is there anybody who can suggest me a way to have everything working?

Thank you in advance
Gaetano

PS: I apologize for the attached traces, but I think they could be useful
