Hi, The USB NIC VIB is not required to be installed separately. The iDRAC Service Module VIB itself takes care of configuring the USB NIC pass-through interface.  Once you install the iSM 2.0 VIB and reboot the server; it is expected to take 2-3 minutes for the USB-NIC interface to get configured. Could you please confirm on the following? 1. iSM 2.0 is supported on ESXi 5.5. However, please let us know which iDRAC firmware version is being used? 2. Do you see the USB-NIC enabled in the iDRAC? Login to iDRAC GUI => Navigate to "iDRAC Settings" => "Network" => Select "OS to iDRAC Pass-through" tab. You should see the USB-NIC selected with a link-local IPv4 address. 3. What are the last 1 or 2 /var/log/syslog.log messages related to iDRAC Service Module? You may search the log using "dsm_ism" phrase.  Thanks, Bharath Koushik
So, there does not appear to be any clear documentation from Dell on how to get the integrated services module installed and working under VMware.  I have a Dell VRTX (12th gen) with an iDRAC7 (enterprise license) in the M520 blades.  I've installed the vib for version 2 on an ESXi 5.5 update2 host - then I found (buried in the iDRAC7 user guide, which is difficult to find itself) that it will only work if you use the "USB NIC" for the OS-to-iDRAC pass-through.  The only thing it says for getting this to work in VMWare is that you must install the idrac_usb_nic vib - with no mention or reference to where to find or get the vib file.  It does not appear to be in the Dell depot, custom image, or iSM download, and Google is not turning anything up for it either. Where exactly does one obtain the vib file for idrac usb virtual nic?
